Feels like a proof of concept than an actual game. Apart from the interesting L-systems, there isn't much to do (only two tasks; reach the top and get points), the ghosting isn't consistent, it's not clear when you are within range of picking a seed (they don't highlight on proximity or anything), Escape does nothing, controls are not adjustable…

I just can't recommend it to anyone in its current state, though I'd be happy to edit this review upon addressing of these matters.
