Very challenging game, good technical implementation and nice polish (wow for world records!). Maybe a lack of visual indications, for instance when you touch blue areas.
Assets are very nice (music & pixel arts), and create an atmosphere. Good interpretation of both themes (keyboard & education). The game may need more gameplay variations (other than left, right, dodge & open). Good job!
Congrats, you mentioned you are a beginner, and the result is very promising! Music and game visuals are fun and cute. Continuity is very good, but the game may need more polish (hide debugger console, etc). Good job!
