Damn this is like an action film xD
What i think could be improved first: the dropdown menus in the settings were a bit too small, there were 3 1920x1080 resolutions (not really important though), sometimes the player got a bit stuck when jumping or something, and also I personally feel like the level was a bit disorienting, or it might be because of the artstyle but I have no idea. Also, the music was really nice but after i left the "tutorial" area and then came back, the music didn't switch back (although it may be intentional, no idea)
Despite that stuff, the graphics and art stuff are really really nice in my opinion, the music is deliciously awesome (although my ears almost fell off when i adjusted the volume slider), the mechanics were nice (especially the breaking wall thing), and its overall just an awesome and really nice game!
