I struggled with the controls a little, finding it difficult and slightly frustrating to actually intuit where the line will go.
But...
Damn, this is gorgeous. The presentation here is stellar. The moment I put a planet down and heard the piano I knew I liked it. The little details like the stars moving slightly and the way planets puff away like clouds are so lovely. I love the name and the whole low-key vibe everything gives off.
I'd love to play a version of this where the controls work a bit better, as at the moment that's the only thing I feel that stops it coming together perfectly. Really nice work!
