Looking great so far! I love games like this, it's similar to Caveblazers.
A few bugs to point out:
Key rebinding does not work. When I pause the game with my
joypad and go to OPTIONS, I can alter music but not key rebinding.
Also, no keyboard control seems to work at all. Joypad only.
I really like using keyboard on games like this.
It works on WINE but it would rock if you could put a native Linux
build out. Gamemaker Studio should be able to export one.
Looking forward to watching this progress! Good work!
Thanks! 8)
