Hi, really fun game, there are just few thing I would like to mention.
1. I would be very nice to ad some basic background, the floor can be empty, but some brick wall or something on the sides would be nice.
2. I kind of don't see the need for the room to have 3 exits when all they do is take you to the map where you again choose which way you want to go. It would make sense to either have one exit and then choose on map, or have map on Esc/M and only choose by entering the wanted room.
3. The difficulty level is quite steep.
Overall still a good game, and take my comment with few bits of salt.
