Thank you very much for your feedback.
I know that the tutorial takes very long, but you will understand why the tutorial is that long when you finish it. It ends after the second enemy stage. You could have reached it by the time of 15 minutes. So you should have been really close to finishing the tutorial and getting the payoff/punchline (don't knwo the right word).
For sure I will take the feedback as constructive, although his final rating was really harsh. It seems that people just expect short games with no story for a game jam. Sorry that we went for something bigger.
