Frogatto & Friends

This is a beautiful 2D platformer which I have been working on since 2009. You can buy it on for $9.99. DRM-free. 10+ hours of gameplay. No internet connection required. Hand-pixelled artwork. Family-friendly. Source available on github.

Candy Crunch

Over the course of two weeks in the spring of 2013, I was commissioned by a company called Ayogo to program a match-3 game. Candy Crunch was the outcome. Match more than three candies together to score a bonus. There is also a double-sized version. You can the game.

Cube Trains

A 3D puzzle game with a train theme, which I made over the course of 2011. It features roughly a dozen puzzles of varying difficulty, and has an expansion pack which grants 11 more. While I considered it rather nice, it was a commercial failure. Comes with editor & player. Code on Github. No digital rights management software included.

Open Pixel Platformer

This project aims to make a free, open-source platformer for coders and artists to use as a resource. I lead the programming side of the project. Code on Github. Discussion is at a sub-forum on PixelJoint.

ComeFrom 2

ComeFrom 2 is an esoteric language which explores the implications of only being able to COMEFROM lines, not GOTO them. Since no stupid idea is any use if it's not accessible, an online IDE is available. Be sure to run the 'Counting Up to Ten' program! For a more detailed explanation and introduction, see the page.

ComeFrom's real coup de grâce, however, is the conditional comefrom. By examining the top variable on the stack, we eliminate the need for if-based conditionals and loops entirely.


A pixel editor demo. You can draw sharp lines on it with your mouse and move around with the arrow keys. (Hold alt and click on the example to grant it keyboard focus.) Infinite scroll in any direction. Features a multi-threaded compositing engine. You can the canvas if you've messed up, since there is no ereaser yet. There is a full-page version.


canvasgame is a demo two-player game, written in Javascript. Controls: a/e to move and o to fire missile for player 1, numpad 4/6 to move and 5 to fire area bomb for player 2. I made the game in one day to learn.
