One Drop Bot

A 3D puzzle platformer available on Steam, Itch.io, Kartridge, and Game Jolt. I developed the game in Unity. Every room contains a new puzzle I designed and implemented. I wrote the code for character movement, 3D camera movement, and shaders. I also created the graphics and sound.

Robert's Run

A forward-running mobile game where you run down a tube avoiding robots, fighting robot bosses, and collecting golden cubes. I wrote the game code and shaders and created the graphics and sound. I published the game on Android and iOS. Currently, the game is only available on the Google Play Store.

Modern Arcana Alpha

A working prototype of a 2D bird's-eye view sandbox RPG. I wrote the code for turn-based combat, a random world generator, custom movement AI for enemies, and all shaders. I created the graphics and sound. I published the game on the Google Play Store.

Game Grumps VS: The Game (Fan Made)

A recreation of a large part of Super Smash Bros. Ultimate, a 2018 crossover fighting game. I created tools in Unity that I used to attach hitbox animations to each move, much like how collision works in the Smash Bros fighting games. I wrote the code and shaders, and I also created the graphics. The game is a tribute to the Game Grumps and contains many references to the show.

Spiral Pattern Generator

A graphical application that generates a random spiral effect by combining the rotating parent transforms of an object Node.js tree. I created this project to practice C++ and build my own game engine. The game engine is still a work in progress, but this project is done.

Circle Pong

A Pong variant with a circular court for 1–4 players. I created it to familiarize myself with Unreal Engine 4 and the C++ Unreal Engine 4 Scripting API. I implemented the gameplay using C++ and created a custom CRT and pixelation shader.

Digital Media Arcade

An arcade machine that can be used to play games made by students. Few students in the engineering department of West Career and Technical Academy and I made this as our final project. I was in charge of creating the software and building the computer hardware. I created a 3D interface with C++ and DirectX. It ran on Windows and launched on startup, giving the illusion of a custom operating system and a real arcade experience.
