played the demo for this a while ago because it looked really unique and interesting and that's exactly what it is! The visuals are beautiful, the music and sound design are beautiful, and each level is a satisfying puzzle to figure out. I usually get frustrated at games like these once the difficulty starts to ramp up but even when this was tough I was always having fun with it, figuring out different routes and strategies and trying to work in each level's hidden challenge. It's fairly short but I can see a lot of replay value here in optimising each level and getting all the challenges, it's absolutely worth your money and your time either way.
