I played and finished all the levels.
It was really fun to try to think of a strategy and use the environment to bounce around!
It lacks polish, but the gameplay and levels are fun to play.
I also had a good feeling receiving the coins, probably because it felt rewarding enough for finishing the level in a reasonable amount of time, and knowing I can use them to purchase stuff.
I actually didn't know you can purchase boosts, I just saw that in the pictures of the game.
Good job overall I enjoyed playing your game :)
