Celeste Classic port to Game Boy

This is a port of CELESTE (for the PICO-8, also known as Celeste Classic) to the Game Boy. In around 8000 lines of SM83 assembly code, which compiles to 29.9kB of ROM and 933 bytes of RAM, this has all of the levels and music of the original game. Since the physics engine had to be rewritten from the ground up, it's not 100% identical.

Has been confirmed to work on original DMG consoles, as well as GBC and GBA back compatibility.  I plan to make a "DX" version supporting color for the GBC. It also works on all major emulators. Enjoy!

"celeste.gb" is the main ROM file, while "build_pak.zip" includes all files needed to build the game, including source code. If you want to make/port a mod, this is helpful.
