The game is simple, and I think it's kind of cute. The balls with the hats reminds me a little of Golf It, if you're familiar with that.
A couple of things. As someone pointed out, when you fall off the map, it doesn't restart, which isn't a big deal. However, I found a glitch - when you get to the big part of the main platform, if you are on the side closest to the spawn, and are touching the conveyor belt on the far right and press jump at the same time, the game just... restarts. Additionally, I found the final ball first, and he congratulated me on finding all of them, which isn't a big deal, but may want to be careful with hard coding dialogue like that in the future.
Overall, good job, was a fun game to play!
