I'm not sure that you have realized that you can get stuck due to the next monster being to strong, no way to grind, and then perhaps you run out of gold when reassigning workers to non income jobs. If not permanently stuck, close to. Forcing you to crit your way to more gold / gems. That would make me stop playing during the first 10 levels.
Ok, got some to say about this. The concept was.. good. I give you credit for that. But the jokes! TO bloody rip off from portal, why are you making the best game in fps games suckier than the flawless thing it is?! Portal is THE best game, and then you start taking the "Cake" jokes out of it, and making it timer. That just... makes me wanna put a seagull down your troat.
