Very creepy atmosphere and a fun concept. After a certain point I don't know that I could have kept up.

I enjoyed playing this! The soundscape is very impressive and the lighting also really helps add to the mood. 

Sometimes I couldn't repair the floor when I thought I could. Not sure if there's a location-based restraint on the tiles that I couldn't discern?  I also had a little trouble knowing which tile they got through at the end before it told me I was done for. 

All around, a great game! Very nice work.
