Hanako Games, the creators of Date Warp which I’ve posted about earlier and other games, are working hard to bring even more games to GNU/Linux,
Spiky Caterpillar let me know that he is working to port Cute Knight Kingdom to GNU/Linux and MacOSX and it’s currently in beta testing.
He also said that Fatal Hearts may also be ported (The Cute Knight Kingdom port involved writing a large chunk of a GameMaker runtime for Linux, so the work to get
Fatal Hearts ported should be much smaller – however, he intends to wait for bug reports on Cute Knights Kingdom before starting in on any other GameMaker-to-Linux ports, and he has several new games trying to be written).
