@ImperialUser actually, the auto g/s includes the clicks per second so you need divide your number by your clicks/s if you want your actual autodmg/click. It confused me in the beggining as well...
I loved the graphics, i really enjoy any kind of Tower/Base defense games, but this is really different in some way, worth the time it took loading. 5/5
The best build found by me was
2 Ultimas (to tank)
1 Entropyalien (to heal)
1 ShadowKiller (to damage all enemies)
1 SoulSeeker (to keep the enemies back)
Get all gems from the hp tree and the attack tree and set more attack for the ShadowKiller and the SoulSeeker. Loved the game 5/5 =)
