Prestige Points are messed up (Points available:11 Used: 8, can't buy anything), automation is messed up (shouldn't be able to automate certain things, yet, but I can), These last few updates have basically broken this game.
So far, every time I've picked an upgrade, it picks the opposite one... For instance, Shield level 1 or Rifle Gun level 2. I picked Shield, and I got gun.
I don't know about everyone else, but buying 1k minions to blow on the campaign every so often isn't that big of a deal... The only thing I'd suggest is making the reward souls
Sometimes it's hard to get through a level when the only path has all the monsters for that level in the next room. And occasionally there's a glitch that removes a graphical layer, and I gained a level each monster I killed while the glitch was active.
It's pretty bad when I could kill some bosses faster than killing some regular enemies... As for the easy factor, I pretended I had to ram certain enemies to make it harder.
Occasionally there is loss of control of the "hero", as well as having your minions randomly exit combat can be quite annoying. BUT... If you would manage to fix those problems, this game would be amazing! 4/5
