The visuals are great, they're clear, and you know exactly what to do when you see a new obstacle. It works great mechanically, but it can use a bit more spice. It fits the theme well, and I thought it was pretty fun, although I didn't get very far. 

Interesting game and more challenging when the scope is large. Nothing happens on the 5th stage as soon as I reach the green point. I don't know if that's the way it is intended, but accordingly I don't get any further from that point and I don't know whether that was the last stage.
