I loved the idea and the execution on this game. It is actually pretty hard to manage all those ants, but feels rewarding to grow and upgrade your anthill. I really enjoyed my time with it!
The only thing i would appreciate would be some visual aid signifying, whether an ant expedition has succeeded or not and how many of them will be coming back. I couldn't fully wrap my head around how that mechanic works and was sometimes surprised to have less ants than i expected :Ddd
But that's nothing necessary and i think you have made a lovely game!
