Please let me know if you ever release a Linux version!
A strange puzzle game about matching colored keys and doors. · By
I don't have a Linux environment, but GameMaker *does* have a Linux export target. I can't make promises, but when development on the game concludes, I'll see if it's in the cards to make Mac and Linux builds. In the meantime, I've heard people say they managed to work it into running on WINE with some effort, so hopefully the same would be possible for you. Thanks for the concern!
