They announced that if they hit $150K, they'll implement 'Stories of the Multiverse,' an actual campaign mode! That's literally the only thing missing from the game, and I never actually thought it would become a possibility. Unfortunately I don't think it'll happen. Maybe they'll wise up and make that its own Kickstarter...?
Did everybody catch that since they reached their funding there is a new Omnitron Hero variant to unlock in the game? Either figure out on your own or, right off, you can simply hit the unlock button (none of that waiting a month stuff). I verified this in both the current iOS and Steam versions of the game.
