The game is a lot of fun. Tons of content and things to unlock! However I'm not able to save more than 1 hero layout. It keeps overriding my current one. Hopefully they will explain this better. Other than that the game is awesome! Good time sinker. Sorry, I wasn't aware you could scroll down. To see other save slots. Thanks for the quick answer!

Did you scroll down in the hero layout menu? There are 9 different slots you can save/load.

This game is incredible if you enjoy idle games. One of the best out there, and the gap in possible progress between F2P and Whales honestly isn't extreme. The purchases available aren't predatory and there isn't a case of upgrades only lasting for a period as is common with modern games. Also TBiz is awesome and continually updates it with new and fun content, which also helps new players keep up.

This Developer is nothing short of genius for creating the best idle game available. Purchases are costly but a one off and worth it if playing. There is also constant updates and the Developer is clearly passionate about this masterpiece. Please do support him so he can continue giving us all great gameplay. The Prestige alone is a brilliant on a idle game.
