I like your idea. Searching around and assigning ants for work. It's chill at first. But I feel bored the more I played. When I upgraded the moving speed to 8/9, I can eat everything in a second, even a piece of bread(I guess it's the longest time required food?). And I don't have a goal. What should the player do when I get a lot of power? Maybe cutting the trees or crushing the rocks when I have so many ants.
Some advice for UIUX, telling the player available ants instead of working ants would help. Then, I no need to do the math assigning the ants.
BGM is great. It fits the vibe nicely. Except it is too short. So I feel it's repeating over and over.
Other than that, great entry. Well done!
