The idea of using your points to rewind is actually very original and it could be improved and turn into something much bigger.
The only(and biggest) problem with this game is that is unplayable, sadly. The movement is really poorly made, jumping is too slow and walking is too fast and that makes it even weirder. Collisions are so bad and it's actually impossible to pass a cactus without taking damage. It is a solid good idea but right now it looks like just a prototype. Maybe you should work more on that idea and then make a good game about it.
Did you already checked my game?Give it a try!
