i got past the school level, and got to library level, but i then realized, you need a 'ton of books' but I couldn't make books. I had to delete my save. :(
Right now, The Machine and Supercomputer are basically the end of the game. I'll probably add more later, though! The Machine will probably eventually give you enough resources for a Supercomputer, but it'll take a while. :P Maybe your villas are just near schools, or there are teleporters near schools? Or maybe those kids just have very rich parents. :)
How to get more than 1 person in a stone generator:
Place a stone mine above the stone generator. Add more to get more people (I think). There is a max, but I'm not sure what.
(P.S, I love this game! rated it 5 stars.)
I defeated a mega boss, and the achievement reward...
was a talent reset. I was really happy, but when I got it, it feeling went away. (And I already had 2 talent resets) and the only thing I upgrade is the laser. The talents resets are pretty useless for me now.
