Good idea, but ruined by design mistake
Idea is lovely, realization is also well done, overally it's an interesting game, worth probably 9/10.
Then why is it so boring? Because every time I lose I have to do exact same thing, mainly trivial until I can get to the point that is hard. Maybe its just me being lame, but I'm at 4th stage, I've lost few times and now I just don't give a damn.
I may try many times to overcome a hurdle, but not if that means I have to repeat first part of the stage every time.
If you just put there such option, that after you lose, you can rewind time by 5 seconds and start from there it would be great.
