Here are my first impressions as a new player:
-I have no problem with the Enter to skip cutscenes because the game tells me I can do it in huge letters
-Start Screen is very plain.
-At the start of the game, the instructions are helpful at the bottom.
-The Main Character, Background, Ground, and UI look very good.
-The first blocks that you have to jump over have completely different art and kind of feel out of place
That's it for now, nice game!
