Loved the game, although I totally suck at managing the birds, it feel really well done. During my first solo game jam, I also attempted a DDR style game (with no music lmfao) but I had a hard time making the hits feel responsive and timed well. In this game, the challenge felt really laid out, and that the only thing holding me back way my skill and because the game did not work reliably.
I also agree that once the birds swapped positions or overlapped, I forgot which button mapped to each bird.
Very impressive project to me, fantastic job. If I may ask, do you feel like this game accomplished what you set out for it to achieve? To me it seems like you wanted to make a rhythm game with unconventional controls and it turned out great. What do you think?
