Hey, thanks for playing!
I agree the interaction should be simplified to a single button.
I intentionally left the tutorial hints incomplete to leave a little "trial and error" feeling ( since i admit there's not much to do other than progressing through the level ).
Can you tell me more about how to reproduce that end game bug? I have tested again but all seems working fine on my end.
After the third wind zone and up the tight cavern you should get an ending message and automatic return to start screen when you hit the area at the end.
