Thank you so much for playing and commenting, I really appreciate feedback.
I think it's a good idea of yours to polish the feedback a little bit. I'll get to work on that after the jam. And I know what you mean with the perfect pitch game. I also play an instrument (piano) and was surprised how hard it is to score, especially with time running down and no possibility to replay the note. That's why I chose to award at least five points even if the guess is off by half a note.
What program do you use for writing music for your games? I'd love ot get into that field, but I'm a bit at a loss what to use. I'd be glad for any tips regarding that, because recording myself at the piano via smartphone is not really the way to go (I tried that for one of my games and I'm not really happy with the result). I tried BoscaCeoil, but if you are used to normal music notation, it's really difficult to get into it.
