Far too easy to get stuck when playing for the first time, so no way to restart w/o reloading. The camera keeps moving randomly even when not using arrow keys. The audio is garbled. Right-click does not work.
You should make a sandbox mode for this, I'd play it for hours if there was one
Turning an anthill into a Tower Defense game is a different idea. I have not seen it done lately. The biggest issue is that you should include a tutorial. That would be the best way to explain everything. I had some slowdown while playing. If you removed the lag this would really improve.
Really cool concept and very fun
