Great Game. make it better =)
i really dislike current tactic system. you should change to coward when not shooting and back to aggresive (mostly, dependant on traits and some situations) when givin'em some bullets... i read somewhere in a forum, that there will be changes. good. =)
difficulties are awesome (finally beaten the game in easy mode =)))) ), anxious to unlock Nightmare! mode =)
challenges are very good too. different game expiriences.
tracking system is probably too simple at the moment to say of it as an ub3r feature =) i'd like to see it extended.
i think the game really needs more different types of random levels/rooms. it will kick demon's ass.
also, personnaly, wanna a bit more teleporters =)
