Lots of potential - good work
The game shows a lot of potential, and it could truly become something great if not for a few inhibiting factors.
The controls for using and switching between items are terrible. I agree with several other posters in that a WASD movement setup combined with E to use an item and CV to cycle through items would be a good setup.
The "ending" after you kill the big mech thing was incredibly poorly done. Between the fact that the game just ends AND you cannot continue from your last checkpoint after it made me just want to STOP playing the game (which I did) rather than finish it.
