The theme is very well met and the idea is really nice. Would love to see few adjustments to make the feel even better for example, the ability to restart the game instead of just quit and start it all over again. Also it felt like the victory condition can be met quite easily - which is not a problem, but since you have quite dramatic tunes (that are great for the theme as well) I would expect little more tense gameplay.

But overall this is very nice entry and you did great job! Thank you for the experience ;)

The ants movment is super cool (boids I guess?).

I can see the potential for a great game if the fights are made more interresting and objectives are added (defend the brood/food source...).
