Thanks for you review Josephkhland.
Actually when the jump flag is active the player should not take hits. But yet in the jump beginning it still do. There are another little bugs to fix, but I did not have enought time. And this weekend my son wanted my attention to play with him. It was hard, but he played my game as well too. As soon as the vote time ends I will upload a new version, byt the alway the new version is already half the size. I am ripping and compacting some assets.
