Hmm, there's a core of a good game here. I do like the concept of steering both the sun and moon to meet each other, but the gameplay was very confusing and even when I figured it out, it got kind of repetitive.
More mechanics than hazards that move around randomly would be great! There's no particular reason to move the sun and moon together, so maybe add something that forces you to move both, for example.
Overall, it's pretty good, it just needs a lot more polish!
