Firstly before anything, I LOVE THE MUSIC! It's amazing! You did really good job composing such bangers!
Having that out of the way I don't know what can I tell. Because you chose the simple design of characters, objects and levels you don't need to add more complex things like coyote time or animations. It's simple and nice. One thing I can tell for sure that I didn't like was how you made main menu and level selection. You can't move from level selection panel to the main menu but I think it's an easy fix. But level completion panel could have an option to move straight to the next level.
Pretty solid submission I will tell you that. Quick, simple and entertaining. Keep it up!
And I have small request, can you check out my game too? I think you will enjoy it too!
