I've went to the time portal once, I've got 9 orbs, but I still find myself grinding level 100 for cash! The NG cloud based save works fine... it better! Luckily the game plays itself while you're offline, on whatever level/town you left off.
Since this game takes days or even weeks to accomplish, damn at least add a scoreboard, maybe even some medals! Otherwise, all this fine programming is a very solitary activity for the player.
