What a great game. It's very intuitive and easy to get into, but still has a lot of interesting interactions to offer!
I think the artwork for the player character should probably use thicker lines to make it match better with the rest of the assets. The player character is the only thing that feels like it doesn't quite fit in there for me.
The parallax effect in the background is interesting because it's scrolling faster than the foreground. Feels a little strange, but probably also helps to make the movement feel faster. Was that a conscious decision?
The music is super catchy and I like the humor. The game controls well and is well balanced. Fantastic submission in my opinion! Good job.
