SK/CZ Let's Play
It was fun and sometimes even a bit tense experience. I enjoyed it, interesting take on the backrooms concept.But it would be better with more monsters and more levels. I mean more monsters for every floor, because one monster on floor is pretty simple to avoid. Mainly if there is 10 players, they surely would find it really easy.
Maybe consider to give there an option like when you're playing it single, there is one monster and when playing it co-op, there will be more monsters on each floor. Or to give the option right in the menu so everyone can choose how many monsters they want on the floor.
But good, funny game!
