I really love it, I think with a bit of polish a bit of more content it could be a perfect 2$ to 5$ game.
Something that I would like to see are:
Bars over nests which tell me when the next bug will be spawned
The bugs health
I'm a bit stupid so didn't fully understood the arrow thing, when is good to use it and how to use it properly, I don't know if a my thing, but just to let you know.
Hope you the best, and that you continue the development ^^
