Now that's a unique theme interpretation! Having the playable character and the boss be animated using spinning wheels not only fits the theme well but also gives the game a unique art style I haven't really seen. Though I wish more of the UI and main menu got this art style as well.
The attacks of the boss where simple but fun to avoid while trying to charge up attacks to fight back. The music really helped to make the atmosphere of the boss fight more intense. However, I did notice that the hitboxes aren't the most accurate as you could get damaged seemingly out of nowhere. Also, some of the attacks could deal 2 damage instead of 1 but I don't know if that's intentional or not.
Still though, this is a solid game 👍
