I didn't get the chance yet to play your game, but it is stunning that you programmed a real GameBoy game that only runs on an emulator. Theoretically, you could flash your game on a cartridge and play it on a real handheld. Now that is authentic!!

Made me break out the emulator for this one!
It's very cool that you got this working for original hardware, that must have been an interesting process. I wish there was some sound and more complete gameplay, but making a game that actually plays on a Gameboy instead of just looking like it does is a pretty commendable effort. Thanks for sharing it!
