This is such a good theme implementation.
Building your robot from spare parts you are discovering is so creative and fun. Combining parts into new ones is also great addition. Dark green-glowy environmmnet builds a good athmosphere.
What I was missing was ability to rotate parts in build mode (I hope I just didn't missed a button for it). Unfortunatelly I also didn't get far, because I got stuck in part where you fall down and I guess you need to use nozzles to get over a small bump, but after falling I was always rotated in a way that nozzles were not aiming a ground (therefore no flying for me).
Still - I was enjoying the game and I think I might get back later to try again.
Great work!
