Oh man! Another comment says the dog was too powerful! He crushed me the first time! Got him the second time! I thought this was a really fun game. Watching the gnomes collect water was a really neat addition to gaining resources.
I think the only critique UI wise I have is how small the tree and cloud are in the bottom menu bar. For me, they were about half the size as the rest of the options, number text included.
There doesn't seem to be sound effects at the moment, but I think a throwing sound effect for the lil guys throwing their spears would be awesome and elevate the project immensely with that small addition! Hearing more and more as they build up in numbers would be so satisfying! :D
