Circuit Dude

PC, macOS, iOS, Android, Nintendo Switch

Circuit Dude is a puzzle game with 120 levels that I designed and programmed for PC and macOS. It is soon to be released for Android and iOS, as well.

The gameplay is fun and simple: Help Circuit Dude build an awesome invention by leading him through the first 100 levels, completing circuits and plugging in microchips. After all chips are inserted into their sockets, the exit will activate and you can advance to the next puzzle! What kind of secret invention is Circuit Dude building? Complete those levels to find out!

But, if you're feeling creative, you can take a shot at creating your own levels and even upload them onto the internet to share with your friends!

Fiend Blaster: Robot Journey

PC (1.2)

You're a robot, sent from the future to the medieval ages to fight terrible monsters and demons that are trying to change the course of history! Destroy them with several weapon types before they rewrite history! Be careful, though, because ammo is limited and it's quite dark!

Features include a unique and cool selective coloring art style, survival game mode (endless waves of progressively-difficult enemies), waypoint game mode (time-based scavenger hunt), online high scores for both, 4 weapon types, and 5 enemy tpes.

This game was created for the DSOP Cartridge Jam #3, 2020. Music was created by Greycove and many models and some code was made by Lowlande52.

Kogre's Mountain

PS Vita (1.0)

Kogre's Mountain is a wholesome, family-friendly digital board game. The first player to reach the top of the mountain with all four of their knights wins!

However, watch out for falling rocks! If the spinner lands on a gate icon, all the rocks will roll down the mountain- Getting hit by one will send your knight back to the bottom, so strategize by hiding your knights behind obstactles and other players.

This game was originally greated with some friends, but after losing the source code, I decided to completely recreate it. Music was created by Greycove and joyrok helped spruce up the models with cool materials and shaders.

Arduboy (3.2)

Circuit Dude is a puzzle game with 75 levels that I designed and programmed for the Arduboy in C/C++. This game has been really well received and even recently polled as the best-rated Arduboy game.

To help design this game, I also created a web application to help generate levels and convert them to raw C/C++ code as well as designing all pixel art for the game.

The gameplay is fun and simple: Help Circuit Dude build an awesome invention by leading him through 50 unique levels, completing circuits and plugging in microchips. After all chips are inserted into their sockets, the exit will activate and you can advance to the next puzzle! What kind of secret invention is Circuit Dude building? Complete all of the levels to find out!

I also created an in-game level editor!

Festive Fight

Arduboy (1.1)

Holiday mascots from throughout the calendar must fight in order to compete for the affection of the children throughout the world for some weird reason. This game includes single and multiplayer support. To fight, you have two options: Attack and Retreat. Each match, you have 5 hearts. Getting punched causes you to lose 1 heart. Lose all your hearts, and you’ll lose the match, so make sure you retreat often to dodge oncoming attacks. Different characters have different stats. Some are harder to use than others, so try them all out! This game was created for the second Arduboy Game Jam.

Loop N' Moove

PC (1.0)

Loop N' Moove is a sidescrolling wrangle 'em up game inspired by Texan culture. Take control of your 10 heads of cattle and drive them as far as possible, round them up when they try to run away and protecting them from wolves. Whenever you lose all of your cattle, your game is over.

Use the mouse to aim your lasso, and left-click to power it up. When you're ready, left-click again to throw. Once you've snagged a bovine, slowly pull them in automatically, left-clicking again to cancel. Use the W, A, S, & D keys to move your horse around.

This game was created during the SGDA Game Jam, 2017.

The Cockpit

PC (2.1)

The Cockpit is a retro-style game that pits a lone chicken against raging traffic. The player navigates the busy streets in order to reach the hen on the other side. This game also supports 2-players where the first player to reach the hen 6 times wins- But don't be fooled! This game isn't as easy as Frogger or Crossy Roads! Cars are insanely fast and frustratingly hard to predict. There are explosions all over the place and even cars crashing into each other!

The left player controls their green chicken using the standard arrow keys on the keyboard while the right player controls their orange chicken with WASD.

This game's retro look and playstyle was inspired by older games such as Frogger and Dig Dug. I made this for Windows in GM to perfectly fit my personal arcade machine's asthetics and theme.

The Cockpit

Arcade Machine

The Cockpit is an arcade cabinet created from the shell of an old Golden Tee cab. I created custom decals as well as inserted a converted CRT TV. The control deck was fabricated from scratch with new buttons/joysticks from Tornado Terrys.

The internal components have been replaced with a Windows PC that can emulate other consoles as well as play the custom game I've made of the same name.

So far, The Cockpit has been shown off at Texas Pinball Festival 2016 and 2018.

Chicken Launcher

PlayStation Vita (1.0)

Chicken Launcher is a fun lil' game I made for the Playstation Vita after making a version for the Arduboy, which was inspired by Kitten Cannon, where you shoot a chicken as far as you can. Try to hit springboards and TNT to give you a big boost, but watch out for spikes! Your high score is recorded and saved. If you think you get a big high score, tweet me a pic!

Train Dodge

Arduboy (1.1)

Who's brave enough to play chicken with a train? Stand on the track as multiple trains come at you full-speed... The closer they get to you before jumping off the tracks, the more points you'll rack up. (You'll also lose points for jumping off of the track too early.) Dodge as many as you can, but beware! If you don't jump off in time, you'll be hit!

Arduboy (2.0)

Arduboy Assistant is a program that allows you to manage an Arduboy's EEPROM as well as test several hardware and software components. You can view raw EEPROM data, back it up through the Arduino IDE's serial monitor, restore EEPROM data the same way, and even clear the entirety of the EEPROM data. Additionally, you can do a button test, LED test, sound test, serial test, and screen test.

Image Regradiater

PC (1.0)

This is a program that I made in order to test a new image processing and masking technique that I created called regradiation. In order to use this program, you must input both a source image, and mask image. Both images will have all of their pixels sorted, retaining the location data for each pixel. The gradient mask's color data is swapped into the source image's data, and the pixels are sorted back to their original location, leaving very beautiful results. Images with very similarly-shaped curves tend to have the best results.

Regradiation can look very similar to pallet swapping, but it is actually a new technique. Results can vary greatly depending on the difference between two images' curves. If the curves are 1:1, regradiation is pallet swapping, however the more the curves mismatch, the greater the difference in application will be.

Note that when running the program, the images must both have the same amount of pixels. Usually, this means that the resolution of the two images must match exactly.

PokéFace

Pebble (2.0)

This is a watchface that I created for the Pebble smartwatch using C/C++ with the CloudPebble IDE. It is a recreation of the popular Pokémon Blue/Red title screen for the Game Boy. Like the original title screen, it features monsters being swapped out by sliding out and replacements sliding in. Due to the limitations of the Pebble smartwatch, I had to recreate a lot of sprites in a monochrome format while still retaining their original artstyle. Pokémon featured in this watchface are: Arbok, Arcanine, Blastoise, Bulbasaur, Charizard, Charmander, Gyarados, Hitmonlee, Kedabra, MewTwo, Nidoqueen, Squirtle, and Venasaur.

Pebble Transporter

Android (1.0)

This is a simple Android application that opens the camera on a device and actively searches for a QR code. (The user can optionally upload an image they have on their phone.) The program takes the QR code, downloads the Pebble application or watchface from the internet, and passes the file directly to the Pebble Android application.

This application was designed for developers who use the CloudPebble IDE to compile their code. It cuts out the steps of having to compile the application locally, connect their device through USB, use a compatible Android file browser to find the specific file, then launch with the Pebble application intent.

FanMate

PSP (1.0)

FanMate is a remake of a popular program for the ol' Palm Pilot, originally created by PalmMate, with the same name. The software is a quirky joke program that is described as "an application to keep you virtually cool... as the hot days of summer approach..." My recreation for the Playstation Portable is virtually identical.

This program has almost no functionality, but it's one of the first applications I created, so it deserves a special little place in my heart.

If you have a Sony PSP on 3.XX custom firmware, you should be able to download this .ZIP, extract the EBOOT.PBP file, and run it. (Extract the contents of the .ZIP file into X:/PSP/GAME/) If you are using a newer version, you'll have to pick up a self-signer. Have fun and stay cool!
