It's not very long, finished it in a couple of days. Fun 'brainless' shooter, but lacks variety. Graphics are simple, yet there's not many enemies and bosses. it gets repetitive. Melee combat is useless (not like doom), the level design leaves you puzzled way too often. No voicing. So yeah, it was kinda fun, but feels like a cheap indie project. don't think I'll come back to it.
