Love the graphics. The sound is nice, but repetitive.
I don't understand what the purpose of the coin is if I can just skip it and go to the next level. You should consider that allows the player to only pass if the collect the coins. Or something like that. I've seen a lot of games in this jam that have coins, but the coins serve no function.
Also, I can't thank you enough for allowing me to press escape to return to the main menu. I can't tell you how many games haven't used this simple foresight to save people frustration. Thank you.
Solid game.
