This game is unbelievably well-produced. I could see this being a fully-released mobile game with almost infinite replayability. The art is extremely well-done, and I truly hope that this makes it into Mark's video. I love the animations of the different plant features being added, especially the branch growth. The different nodes on each branch make me feel like I could sit and experiment with different plant "builds" for hours!
I thought I liked my game until I saw yours, now I might unsubmit...
JK of course, but great work!
