Wow! Lots of feedback! So the visual issues were not intended. I didn't have enough time for doing too much bug fixing or stuff like that but when you can not move forward, that is intended. If you talk to the joe the cube(probably should have explained that. You press space next to him and you can talk), he will tell you to keep going left again. then there will be a hidden passageway in the wall. oh and this is a two player game but a single-player version would have been very cool too!
