1 word: Frustrating. 3 words: Easy and Frustrating
The game is rather frustrating the first few tries. That is until in each level you've figured out how best to zerg with the green factories. That's it. I was at a loss as to why there were so many other types of factories, since all they produced were weak and slow, or weak and fast bots.
I have to say that the lightning storms sitting right over the gate to the battlefield and frying each and every bot made is beyond annoying.
The most frustrating thing that I saw was the lag-induced stoppage of production of bots on my side, while the enemy bots rolled right on through to my wall. (Unless this is some paid-for special attack the AI gets that the player does not...?) I suspect not as it only happened if I wanted to scroll over the battlefield to see what was coming, and, I said before, once I had the right green-factory zerging pattern down, I didn't need to bother watching.
Simplistic graphics. Minimal sounds effects.
No medals either?
I wish I had something positive to add, but I'm afraid I'm drawing a blank.
