I hate how enemies respawn on the later levels. The elite hackers are the most dangerous, so why should I bother killing people after I kill them if there's a chance a new one will spawn? Especially since killing stuff uses precious cycles.
I think the AI should be improved. Those robots start shooting you before they see you, and when they come equipped with rocket lunchers it becomes a little difficult.
Can't wait until I'm high enough to try lolmarket :D Oh, and in the achievements, could you please put commas? They get a little hard to read sometimes.
