Congrats on finishing your game! Well done!
I think my favorite part was the little characters. You did a great job with your assets and making an appealing little level. And I really liked the Sonic inspired run animation for the main character. Get fast enough and you're just a speeding ball!
I think instead of the number at the top determining your velocity and helping the player figure out if they're fast enough to take out an enemy, you could have change your player sprite. Maybe don't change to the ball unless you're going fast enough to kill an enemy? Or sparkle/particle effects if you're going super fast? You've got such a great aesthetic going that it felt a little just pasting a number up top.
Ultimately, I couldn't get more than to the second level. The controls were just a bit too much for me. While the jam theme was about randomness, my player control feeling random just wasn't fun to play.
Good job on finishing your game and submitting. Keep making games!
