Nice that you put a 3d jump and run together.
Unfortunatly I dont really see the theme in this game. Also the controlls are very clunky some times. I couldn't find a way to reach the top of the big room (I was stuck somewhere on a platform half way or less up). The base resolution is with 1920*1080 way to big for a browser game and even for an desktop game if you start in window mode. Nice that you had at least a full screen toggle to adress this a little bit.
