Interesting concept...
It took me a while to figure out that I had to reach capacity before I could actually deposit the ants in the designated drop-zone area. Maybe explain that better in the instruction, or make it slightly more challenging and take off this requirement. Overall good game, things that could've made it better and possibly more challenging would have been varying back-drops... like some back-yard type graphic, then maybe make the ants colors that match the back-drop, so that you really have to pay attention to see them moving...
