This one hooked me for quite a while, but I am a sucker for "number goes up" kinda games. It did feel like the pace of the game never really changed, the ants had more health but the extra damage I had more than compensated for it. It seemed like I could've just gone on forever without losing any lives. It would've been cool to see the spawn rate REALLY ramp up so you have to actually manage your time rather than just go one at a time in any order and it be fine.
This is where I stopped in the end, I had a good time but would've been even better if there was a bit more challenge!
