Move with wasd through the passages press p to pause (it looks like it's frozen atm) This actually (surprisingly) plays best in full screen :O just make sure you don't have other stuff open etc... *new* shadows and stuff on the walls, better sounding footsteps, quieter music, probably something that I missed out :P press the down arrow to go to your really bad inventory, and arrow keys to select while there! (It doesn't do a lot so far)
THIS IS NOT FINISHED AT ALL it's part of a collab that I'm working on, so it's not really worth requesting stuff :P
