It seems really cool. Odd that it is a DOS platform game but it says its requirements is Windows(?).
Have you heard of http://www.dosgamesarchive.com ? They have lots of DOS games (older ones). One can even get them on a cd-rom (which I did ). I have not tried them yet but DOS games usually work in DOS full screen in OS/2 (at least the ones that I have tried [Doom, Quake - DOS version, Hexen, etc]).
OS/2 Warp-ed to the very end.
