Great game! The graphics are outstanding. I liked the control scheme, reminiscent of the Nintendo. My only concern is that there's not much "collaboration with the AI"; the AI is simply another player's skill. I also wish there was a bit more content. I felt the game finished before it had even started. But alas, this is a GameJam after all. The movement felt smooth, and I reiterate how good the art was.
You should feel proud of this game, and I encourage you to expand this project.
Congratulation on your submission!
