I had a lot of a fun playing this game, and I loveeeeee the music for this game! Might be cool if the monsters had collision with the barriers and bricks.

Ah yeah, survivors-likes generally have the monsters warp through everything intentionally, so that the player has to be careful not to get stuck somewhere. It's why there are a couple of rooms in the game where you need to walk around obstacles to get to chests.
Also it has pixel perfect collisions, so it would be quite slow to have 100 monsters doing that (believe me I tried!)
