Visually, this is everything I like about games. It's adorable! Every bit of it shines. The cute witch sprite, the bobbly ghosts, and little peppermint candies. The limited palette is wonderful, and not too stressful on the eyes.
The controls are both great and tedious.
On the one hand, I love their simplicity. Lunging down and floating up. You only control your movement forward.
On the other, it takes a bit of time to get the hang of and even then is frustrating.
It would be helpful if your time in the clouds came with an outline, showing where you are as you drift down. If this was to be fleshed out more, I'd recommend a tutorial showing where you'd fall to help people with the idea.
But for a one off game jam design? This is really delightful, artistically compelling, and an addicting experience to try and beat your own high score. It'll charm the pants right off ya.
