In the current verison of the game there is a bug that makes the game kind of impossible. I personally don't have a problem with it, but if you want to play the game normally  play 0.2.0.4 instead.

This is a fun bug, it gives the challenge to good players and it's possible to pass

I have problem different problem:Then i exit the stage  i cant continue previous run

well, i would say, if its not game breaking and its a challenge that people is enjoying i would say keep it but hopefully as and option and not mandatory from now on
