Scrolls only gave Mana Production after getting the 'empower frog' upgrade. If this is intentional, maybe the tooltip for scrolls could say such?
All button is a MUST for Wizcoins.
Repeating map, I mean that when you complete the map, and are at the Rewards screen, it could give you a button to 'Repeat same map' This way you don't have to go back to the Map menu and re-select/start the map.
This is also what I meant for 'auto-progress', like when you defeat a monster in Map, you have a option to auto-progress onto the next monster. Not off-line gains (although would be good), but instead you can start a map, and then progress through the monsters.
For the autoclicker, I had it sell everything that I auto-produced (bugs/herbs i think at the time) and then buy Wizcoin. This way when I woke up I had a bunch of wizcoin which I could sell when it was high. Wizcoin has no maximum so it was the only thing I could invest into and receive benefits when I was actively playing again. Also clearing a bunch of space was also good.
