Glad I tried this again with the new scrolling controls because I quite like this style of idle game and it doesn't hurt to have more of them.
I didn't need to prestige to beat the demo, but when I clicked prestige after the results, every building apart from the statue was gone, including the tavern and the well. The eggs think it's still there and don't move past the spot where it would be, but there's no way to do anything now. Funny, but clearly not intended unless I'm missing the way to bring them back.
