What a pleasureful game to have! The theme is at its peak here and levels are progressively harder. Controls are intuitive, this is perfect. And phisics always make a game fun as hell. My only thought is about pixels. I know how hard it is to work in Unity with pixel grid, yet it adds consistency to the visual. Seeing sprite of the flybot hand rotating diagonaly made me upset. So did some minor edges in the levels. And I whould love to see some background here.
Still, gameplay is a gem.
