Very nice polish to the game! The color palette fits the retro vibe SO well. I found some of the sfx to be a bit harsh on the ears - especially the mouse click that shows you have to click on the character. This might be more of a personal preference, but for such a simple game mechanically, I would have liked to see a very simple UI layout. When you finish a level many buttons pop up on the screen with varying text sizes and layouts. I felt it a bit cluttered for how retro a feel this game is.
But those small things aside, this is a top tier entry for a game jam! Very impressive you were able to scale to so many levels in such a short amount of time. You must have really designed the code and structure of the game well for you to be able to create so many options! Good job dude!
