@123123123123123 - I feel your pain, I was trying to get about like 10x (I made my multiplier rise) and I had 13,000,000. It just had to stop at black?

I found out a way to get the hard badge. Once you beat a level, you have to press Esc. as FAST as you can. If you're quick enough, you'll actually pass all the levels and even pass the cake room level.

I thought Prestige didn't work, but I actually now know that it doubles your game experience. Like you can only get 10 miners on the first playthrough. 1 prestige later, you can get 20, etc. Also, you can get more upgrades to boost your experience. Have fun!
I'd like to file a complaint, mister creator. I was just playing a normal game of Survival Idle with me until I went to Lethal Lava Land and the owl cuts off the board to Ganon's Castle. Fix this in the future?
