The controls take some getting used to, but the Joust inspiration shines through-- manageably slippery, heheh!
I love the graphics. They're simple, stylized, and very cute-- it fits the overall atmosphere tremendously well. Everything feels very fun and lighthearted without trying to be cute, and I love that.
While some of the platforming without your Osmu can be a little frustrating, I think it's a solid idea with a clever, adorable mechanic that I would absolutely love seeing a full release of!
