Loved the vibe and charm of the game! I think the music choice and graphics actually fit idea very well!
As people have stated I do think the camera scroll could be a bit faster at times, at others it was good enough. One idea I give you is make the scroll speed dynamic, as in if the player gets to close to the right side, make is faster! Also if you wanna make platformers again, Tarodev on Youtube has a video explaining common platformer mechanics and how to implement them in code, maybe it could give you ideas for your own character controllers in the future ^^
Great work, keep it up!
