Tried the latest build with the "Lively Meadow" area and think the caterpillar and hummingbird combination is wonderful. (^-^) My hands hurts when there's too intensive clicking, but this version made that easier for me. My favorite moment was seeing a caterpillar sail on a leaf to eat all the plants in one of the ponds. x)
Later in the game when I placed a lot of the caterpillar attracting plants in one place the caterpillars became dormant though. They just gathered there, a couple of them and didn't turn into butterflies. Maybe it was because I reached 100% clean air, but still I'm not sure what happened.
Thanks for sharing your game! (^-^)/
