I would have to agree with everyone else, the bugs needs to be fixed, otherwise great game.
An addition that would be nice though, would be the possibility to bulk upgrade your working slaves.
The first game was awesome, but this reminds me more of a cheap knockoff of that, than an actual sequel.
The controls are quirky at best, the enemies are to randomly behavioried to have any predictability, you can never find you crosshair which for the most part squirms around the screen like an epileptic lepper.
