NOTE: I am currently developing a sequel! See Word Slide Puzzles Plus below.

A word game based on the classic "15 sliding tiles" puzzle. Slide the tiles to make as many four letter words as you can in the allotted time. Includes three themes and six pieces of music for either an energetic or relaxed gameplay experience.

This was my first finished project, completed in three months (on and off). The Android app on the Play Store has over 5,000 installs and zero reported ANR/crashes.

A Game Boy emulator.

The Game Boy was released in 1989 and is powered by a z80-like processor running at an effective clock speed of 2²⁰ Hz (~1.048 MHz). It features two background layers and one sprite layer of up to 40 sprites. Find more general information about the Game Boy on the Wikipedia page and more technical information on this GitHub page.

The emulator is "complete" in the sense that it's at a state that I'm very happy with. However, it isn't "finished" by any means... There are still compatibility issues with some games, and I also haven't worked on implementing sound at all, or Game Boy Color support (they were out of scope of my goals from the project).

However, I am still incredibly happy with what I've accomplished. It can run several of my favorite games, including larger, more complex ones I didn't expect to work like Zelda: Link's Awakening and Metroid II.

An interpreter for software meant for the CHIP-8 virtual machine.

The CHIP-8 is a virtual machine from 1978 which has 35 opcodes and includes a graphics system. For more information, see the Wikipedia page.

My interpreter appears to have an extremely high level of compatibility with CHIP-8 software, with the exception of software that makes calls to the underlying operating system.

A vertical "shmup" game with very simple gameplay. Help Yuko destroy her schoolwork and responsibilities so she can have a fun day off. Features two difficulty modes, Google Play integration (achievements and leaderboards), Google+ sharing, and a gallery that shows your progression.

The game was completed with a partner whom I collaborated with via the Internet. (See her portfolio here.) It is a very small game with a total of at most two weeks of work put into it. Some notable features include Google+ integration, leaderboards, achievements, and several scaling and filtering options to make the pixel art look good to the user.

The upcoming sequel to Word Slide (2013). In addition to a brand new look, this new game features various individual challenge puzzles to complete.

I anticipate to finish this game by the end of 2023.

A puzzle game in the vein of action puzzle games like Tetris and Puzzle League. The scope of this game is larger than any of my previous projects; this includes hired musicians, artists, and voice talent.

Due to various factors, it is currently on hiatus. However, I plan on returning to this project in the future.

A smaller, mobile-focused spinoff of Sol Stone Swap. This solo project started due to various factors (e.g. the COVID pandemic) making it tough to coordinate with others on the larger game.

This game is mechanically very similar to Sol Stone Swap, but with a more relaxed single player focus. The player is no longer battling against another player, and can instead take their time focusing on getting large combos and high scores in a low stress single player game.

A completely unofficial Celeste port to the Game Boy, written in assembly. It is based on the original, free PICO-8 "Celeste" that is also included as a bonus in the beloved 2018 game. (See a video of the original Celeste or play the original Celeste in your browser.)

It is still very early, but I have included it here because I'm very proud of my progress.

Technical challenges:

• - I am fitting the entire game into 32 KB.
• - I have implemented an enhanced run-length encoding scheme that compresses each 20x16 screen to approx. 150-200 bytes.
• - I developed a Java tool to encode levels made in Tiled to my custom format so I can add it to the game.

A horizontal "shmup" game.

The game was being worked on with a partner whom I collaborated with via the Internet. (See her portfolio here.) One particular feature that is a milestone for me is the collision detection handling. Instead of using the easy AABBs, I implemented polygon collision detection and a broadphase / narrowphase for optimization.

I created several tools to help develop this game, including a level editor for creating levels and a bounding polygon editor for creating the polygonal bounds of level blocks / tiles for collision detection.

The project has not been completed because my partner wanted to take a break and start a very small and simple game, which became Yuko's Day Off.
