Get Off My Planet Amazing but never ending.
I played for like an hour straight and got to about level 121, got past the first level 50, the next level 50, then got to level 21 on the 3rd round of 50s and I got owned. 4 obliterators, 25-30 triple lasers, +100 power, +12 gold, and all the power ups from the research facility. You just can't do it. The green bosses after the 3rd round of 50s is just rediculous. Over 200,000-500,000 HP and does 1/3 of that damage to your buildings. Added to the fact that your buildings get damaged even when the enemy explodes is a let down once you get the max workshop which is only +50. You should let go of the max workshop and make it unlimited because as of now, at the end of the 2nd round of 50s and the 3rd round of 50s, you have to constantly be rebuilding you stuff because it keeps getting destroyed even when you kill the enemies fast enough.
Either remove the workshop cap or just make it end at the first round of 50 which is easy lol. I'll try it on regular next time.
