I really dig your little bit of story. It fits the theme well, and is the right amount lighthearted do fit the cute art style. Actually, something about the story and art style sort of give me Kirby vibes, which is a positive if you ask me.
The attacking mechanic is interesting, and I think it has potential, but I'm not sure that it reads very well right now. I feel like it's sort of ineffective at really combating the enemy, and makes the player feel kind of weak. All that said though, I think this kind of interesting mechanic is perfect for a game jam where you can try new stuff and play around with it; just offering some feedback in case you have any intentions of expanding this.
Great work!
