Nova the Squirrel

Nova the Squirrel is an NES game that stars Nova Storm, a green squirrel, who ends up in a strange world at a convenient time, and has to use her new abilities to save it. It's a platformer that mostly focuses on Kirby-style ability copying and puzzle mechanics.

This game is completely open source. The engine is GPL licensed and you may use it to create your own NES platformer games, and all of the accompanying tools, while lacking user friendliness, are open source as well. You can freely distribute or sell your game, as long as the source is also provided.

Tilemap Town screenshot
Tilemap Town
A recreation of the old BYOND "building game" genre of games. So far players can connect, register, walk around, and build on a map together. Later players will be able to create their own maps with permission settings they choose, and upload their own graphics and player sprites. Work in progress.

FHBG SDL screenshot
Forehead Block Guy SDL
A C rewrite of my earlier
Forehead Block Guy for NES that I wrote in 2011, except a lot cooler and way less buggy. This is a simple platformer where you go around launching blocks from your forehead (hence the name) in order to defeat enemies. Some levels involve defeating all the enemies on a level and some require you to collect a certain number of Doritos.
This is still unfinished, as I started running out of ideas after I finished the first world and with the new, more complex level format I never finished the level editor. I was originally writing this for the nD but since that's dead I'm actually working on a Game Boy Color port instead. I will update about that here once that's done.

Conway's Life screenshot
NES Life
Very fast implementation of Conway's Life for the NES with a 32x32 grid. Originally I wanted to reverse engineer how Video Life manages to be so fast but then I decided to just try and make a Life that takes advantage of how much more space you get in an NES cart.

Conway's Life 64x32 screenshot
NES Life 64x32
An implementation of Conway's Life for NES that's slower but has twice as big of a grid, and lets you choose between different rulesets.

Conway's Life for Game Boy screenshot
Conway's Life for Game Boy
This is a fast version of Conway's Life for Game Boy. It has a 32x32 grid and uses the same algorithm as the 32x32 NES version. Supports Game Boy Color, allowing you to switch to double speed mode, and has a 64x64 grid mode that doesn't currently work.

Forehead Block Guy
My first complete NES game that led to DABG and that sucks and has horrible code, and that I wrote when I was 15. I'd recommend checking out the
SDL version or just playing DABG which has most of the same gameplay.

Sound effect editor screenshot
Sound effect editor
Sound effect editor and previewer for games that use the sound engine from Thwaite. About 3 kilobytes in size. I recommend
the editor by Tepples instead.

Mario Funk
Mario Funk
A really old hack of Super Mario Bros that changes all the levels, lots of palettes, graphics and even the music. There's a mix of a disco theme with Youtube Poop theme and this was the first game of mine to have flying cheeseburger enemies.

Joshcraft 83+
This is a very simplistic tile-based platformer for the TI-83+ and TI-84+ graphing calculators where you can walk around and place/remove tiles on a 48x16 map, which you can save or load to 9 slots. Oh, and you can draw up to 16 of your own block types.
