Progress in the last couple of days:
+ Finished two more dungeon rooms (just one left)
+ Added three pressure plates that need to be activated in order
+ Added falling down two floor below
+ Fixed issues with doors closing and opening directly after entering a room
+ Fixed facing issues when falling down a floor
+ Redid the shadows for frozen/stone enemies/containers
With that I believe I'm more or less ready to release the new demo. Just need to remove the tester stuff. There are still two small issues that I'm working on, but that's always the case
