It was pretty fun trying to figure out how to get the corner coins from the final part of the second level. Would be helpful to show the controls on startup.
Was tough jumping in the tunnels with the spikes, if you mis-jump, you can get stuck and lose all 3 hearts without being able to recover control.
I can't figure out how to get the last 3 coins on the third level, do you have to double jump from one spring to the next?
