sooo Easy
idk what yall are talking about this has to be the easiest game out there. just upgrade your robot spawn to 6 have your air robots at 4 then just pile one health and attack for ground units. keep hurricane repair and sentrys. thats it! smash 1 and 2 the whole time you will crash the shit out of the game but you will be unbeatable Zerg Rush FTW!
on a different note. this game is shmeh the overall feel is just boring and unoriginal. if you could possibly fix some issues with the bugs like polo had said firing at dead spheres and the almost wow waiting for cooldown feel. then this game could be great but overall a good time waster and a nice array of upgrades. but overall needs some more work. :)
