I mean the idea is good but arent there places where you have to rewind or else you cant pass for example in "rise and fall" or at 5:22 at my run?

While under normal implications yes, however if you read the rules there are certain instances where you are allowed to rewind (Such as falling of the map) that make it possible.

I read the rules before but just thought that if you are allowed to rewind when needed, the difference to a normal run would be minimal and kinda unnecessary
