The most stylish game of the jam that I've played thus far. What a fantastic menu. I loved the ambition here, and how it was pretty much achieved. Bubbly music adds so much to the zany art and UI. The progression of obtaining characters with accumulated score? Amazing.
I feel the gameplay programming, including the arc of jump, and the level design are good. The main issue obviously is that the visual design of the level makes no differentiation between what's an obstacle and what's not, nor what's a foreground interactable vs. a background object. As a result, the gameplay at present is mashing the jump button hoping that you successfully hop over an otherwise unidentifiable obstacle that's going to take a heart.
But almost everything else is done right. The character model and animation is beautiful, and the environment is as well. It just needs to be slightly more optimized for understandability.
This is excellent style and premise, however. I hope you guys continue to work on it—I think you have something here.
