Thanks a lot for your feedback!
I completely agree with you. Unfortunately, I did not have much time work on it on Monday. Therefore I did not have time to implement a real tutorial level. I should probably have done it when I was testing the controls already. But doing it at the end would have taken too much time.
To at least have something I just really quickly implemented some pictures and text as a tutorial ;)
I would like to add a better one to the game when the Jam is over!
