Just played this one. I think the fundamental systems are working well. My only real feedback is that it's a little bare bones in terms of both style and content, which tbh I think is fine for a game jam entry. Something that might be fun would be using this movement system to actually get _to_ the caves. In other words, you could start in space, some distance away from the moon, and navigate to moon. You can use your imagination here, but there could be challenges in the form of hazards like space debris, asteroids, gravity wells, etc. But yeah the fundamental concept is good, just needs fleshing out.
