As many others have said, way too much money grabbing, but aside from that, I can't ever buy an upgrade. I collect 50 blops, get the message that says go buy an upgrade, it highlights it like I can buy the first upgrade, but when I click it, it says "can't afford" and suggests I pay money to upgrade. Tried multiple times, refreshing, etc. Suuuuuper lame.
HAAAAAAAAAAAAAAAAAAAA!!! You don't mind if I use that for some dialog in Boss 102? That would be hilarious! Thanks for the play and the comment! Best, -Tim
I'm also stuck. I'm in the lab area, I think the second floor I fought a cyborg type guy and when I came out of the battle, I was stuck : ( I'd love to keep playing since this is a great game.
