Graphics and game play are both really nice. Saw in your devlog, that you were optimizing the rendering lately. Everything is scrolling and moving smoothly - good job on that one. The Loading Screens were kind of surprising. Maybe you can just preload all adjacent scenes in the background once player enters a new scene - to make transition instant?
I missed my W/A/S/D key controls - having them in-game (as a secondary option) would be nice.
Other than that - great, polished game!
