Wow, thanks a lot for playing my game and providing the nice feedback. Yes, maybe the Coop-Mode could be a thing :). I had already some friends of mine playing it with two people and they got a score of 40k :).
Wow, your points are amazing. For your first tries the points are already great, but your 36473 is the highest points I have seen so far, when it was played by only one person. Congratulations. Happy to hear you had some fun trying to beat the highscore!
