I think I may have found it.
Sometimes when there's an obstacle on the side, it gets a little into the obstacle.
After that, the jump stops working.
This happens when I am using a lot of jumps.
OK, Thanks, i will check this und fix it.
Hi Fish, thanks for your Feedback. I updated the game with controller support and fixed the problems.
I beat the boss and got all the levels complete.
I used a game pad and it was easy.
It was fun! Thanks!
