Very cool concept! I really like the approach with tetris.
Just a few things I noticed:
- A small sound before I switch to the conversation with the shady benefactor. To tell me I'm at the end of a level.
- Some times I would click on a leaf and it would not flip. Not sure if that was a bug, but just wanted to point it out.
Overall, I loved the game mechanics (I would see it as a mobile, that crap is hard!). I had a little hard time understanding the tutorial at first, but on the second run it was okay. It was pretty clear.
Very good game, cool story and mechanics!
