the game didn't work with keyboard or mouse (for me at least) on the web version. i was able to use an xbox controller to play, but that could make this inaccessible for some people to play. the game boy authenticity was cool to see though!

Yeah, I’m never able to get GB Studio games to play on a computer browser. However, if you play it on your phone it will actually give you a Game Boy controller beneath the screen so that it looks and almost feels like an actual Game Boy.
To play on a computer you would have to download the .gb rom and play in an emulator.
