this is the game i am developing at the moment - it is basically an excuse to learn openGL (and hence is my 1st opengl venture).
the level deformation is incredibly slow at the moment (see: http://www.opengl.org/discussion_boards/ubb/Forum3/HTML/002078.html
for a description of this problem) so i recommend you disable it using the options menu.
anyway - what do you think?
(check out my text file based menu/particle systems, look in “menus/.mnu" and "emitters/.emi” for examples).
windows only at the moment im afraid
