Also, where is the Cancel button on the profile page?
Does the game run in the background or does it need to be the active tab?
Ah sorry I missed this!
Ah, yeah the game largely becomes an idle game eventually where discovering the next area and finding the next unlocks are the progression. Because this was originally made for an audience that wasn't too familiar with games/idle games were still relatively new when this originally released (back in 2015), we didn't go too crazy with different mechanics.
The profile page is for some light customization, but that is a good catch if you want to revert your changes!
The game should run in the background if you tab away to surf the web.
