Ohhh, now I get it! I didn’t realise that, the game is so much clearer now :D Too late to change my rating unfortunately, but I could at least see more of the game
You may want to not save the velocity at checkpoint, for some reason I got stuckat the checkpoint before the first stairs (after the big jumper) as it would respawn me infinitely at increasing velocity throwing me to the wall.
But gameplay wise it is a very good idea
