Hey man, nice little game! I really like the concept of the mimic. I feel like this game could tell a very strong story.
Two things to improve: You cant get rid of the mimics once you spawn them(except for changing scenes). So you might add a mechanic to lock them out or something.
Second: I thinkg this game could benefit from well placed lighting. The flat look took away some of the creepyness you tried to convey.
A cool submission nevertheless!
