Amazing game, even now!
Couple of things:
- My first "a-ha" moment was when I realized that roots indicate where the water is and don't die by themselves
- My next "a-ha" moment was when I checked tree gallery and realized that roots can intersect. Felt like cheating. I love it! It's mother nature, everything goes!
- Removing of roots/braches doesn't work for me
- There's no update system as far as I understand.
I'm not sure if you still work on this but if not I would urge you to publish the source so it does not go in vain.
