Oh,HeLL!
Currently our only product, this game rocks. It is based on the Crystal Space engine. Screenshots will soon (in a few months) be available on the Oh,HeLL! Webpage.
Specs:
Great special effects (fog, real mirrors, curved surfaces, particle systems)!
Great single and multi levels!
Tons of different monsters and enemies!
Amazingly (un)realistic scenery!
Coming Soon: lens flare effects, and more advanced addons to the already great Crystal Space engine!
