Great idea
The skill system is great, but it's true that the game could be faster. The whole bug game idea is great, every body has a favorite bug, so letting the player choose wich creature he wants to play with would be a even greater idea. It would be really cool seeing a spider fighting a scorpion or something like that, specially if you took the game to a action/adventure style, where you would be going through the jungle/forest/desert fighting the other creatures.
You should consider doing a game like that, I believe it would have a even bigger acceptation.
Keep up the good work!
