Thanks a lot It was some kind of puzzle ahah I was too quick to think it was a bug.
By the way this is a very neat game, it reminds me when I was playing with my brother he was holding an action figure and I was mimicking blades with my hands and I was telling him trying to go ahead, don't know it reminds me of that, plateformers with time precision to pass are always fun to play. I also love the checkpoints.
The only thing that I have to report is that sometimes the ball is suddenly bouncing in the other direction when It touches the ground.
