I've never had so much fun playing with balls... except maybe that one time..
On a more serious note, I think you did an amazing job.
The physics are just right to make balancing on those thin rail sections really tense.
although the art style is somewhat simplistic and you mentioned that you didn't get all of the art done, you did a solid job making every asset work together, nothing looked out of place. I think the music you picked also tied in well with the art and theme of the game.
all around solid work!
I did not, unfortunately, beat theVengeful's score.
