Yes, ended up trying to bugfix as much as I could by the deadline. Thanks for playing!
I bet you ran into some bugs because I didn't disable the keys I bounded for testing (wasd/up arrow). This 3 button limit was crazy!
The limitation was very difficult to work around. Thanks for clarifying about the inputs. I thought the wasd was doing something but wasn't completely sure. I think if you don't use wasd the game runs fine and is enjoyable, but if you hold s as soon as you start, you would fall out of the map. What's funny is that you can still shoot the enemies while under the map.
