The polishing is just amazing. It's a simple and fun game, but the effects, sounds, and visuals were all on point. All the feelings that the game was supposed to convey were captured perfectly. Normally, I would suggest some ideas to improve the game, but the concept is so well executed that the most you can do is make minor balance changes, such as increasing the player's speed.
The only problem is that when you lose, you have to wait a long time before getting to the interesting part again.
