I like the coin placement, using the most of the mechanic by having the player have to extend as much as possible to get more coins but then risk dying due to your bigger hitbox

Fun idea, I feel like this really embraced the spirit of the prompt and made something familiar but with a new spin. 

I found a rather game breaking bug where you can beat the game without moving!

You can boost your jump by jumping, scaling upwards and then scaling down again. You can jump over every wall using that :D

Keep making games, this is nice for a first project!
