it was fun, not very original. but easy. like the devs might not know but if you shoot from behind the room a ton of bullets, everything is killed and less bullets attack u. U just stay safe in the corridor, and if a bullet just happens to go your way, you go back a bit until they disappear and go towards the cleaned up room. ez.
fun but not unique as I played many games with this trait of ricocheting and multiplying bullets before. Thanks still!
