This is a neat idea! I haven't seen anything like this, and the idea of predicting the movement of the match has a lot of potential. The main problem that I ran into was the seemingly random rotation of that match at times - there were a few times where the match would go down the exact same part of the river but get stuck in completely different places just because of the rotation. Aside from that, I had a lot of fun with this! I especially liked the art and music, which added a lot to the overall experience. I was impressed when I saw that you made it all during the jam, so really well done with that! Nicely done, and congrats on submitting a complete game!
