I know this is a bit late, and all support for this has most likely stopped, but what if you can skip more than 1 stage if you've completed the level before? I feel like that would be helpful.
Uh, so I would ask chat, but it won't load for me. I have 19,663 Tickets but I can't use. How exactly do I soft reset? I have a Natalie Dragon, but no Nate Dragon. What do I do >.<
If you're using Chrome, you may need to enable Flash so that you can connect to the Chat websocket. I had to do that the other day. Nate Dragon is the 20th Crusader. If you're using Detective Kaine and the Golden Panda then you should be able to start buying levels for him around area 70, and do your first reset of the world around area 85. Most players try to reset when they have 7,500 total levels on all Crusaders, for 15 Idols to tackle the next objective.

There's a "delete save" option on the pause screen, among a bunch of other settings
