Huh. I'm a bit confused on what the goal of the game actually is, but I do appreciate the simplistic nature of it. I didn't realize it right away, but I like the fact that the scale zooms out when you split your stem more. While it does make things easier to see, controlling multiple stems is quite difficult to maintain for more than a few seconds.
A vision is certainly there, but I think the execution needs a little more work. Keep at it!
