Cool mechanic, I liked it a lot. The art, audio was also really great!
The only complaint I have is that it is not easy to grab ants, I suggest adding a bigger collider for the hand. Later, I saw a dot on the hand, so it became a bit easier to grab them, but still, I think a bigger collider would make the game way more fun.
All in all, the game was fun and interesting to play, good job!
