Yeah the graphics looks great and the core idea of the game is also very good.
However, there are so many bugs in the game and stuff that makes it a bit unplayable. Maybe another week on this to fix those issues and you got yourself a great game.
Several walls have no colliders and you can just walk through them.
Upon dying and reloading a save state things break totally. Health pack did seem to heal any.
You should add on your instruction page that ESC is also used to close some UI stuff, took me a while to figure out.
Still a great game entry to the jam!
