Characters look AMAZING! I like the concept behind it.
There were a few things I didn't understand however. I couldn't figure out the combat system at all. I also ran into some bugs, one of them game breaking. After I get the grow ability and have to return to the burrows, the plant where there are two ants can't be grown.
The controls are a bit floaty. The platforming section to get to the grow ability was quite difficult because my character kept sliding off into the water.
A combat tutorial would have been really useful. I'd love to see the concept developed further.
