Thanks for this great feedback, I've been trying to figure out how to reduce the amount of pop up, I think there may also be too many quests, especially as each upgrade of each area has an associated quest. I've modified the game to no longer show quest pop ups, instead a new quest icon pops up to let the user know that a new quest has arrived so they can go to the quest at their leisure. Quest complete pop ups are still there though, not sure what to do about those yet. I'm a big WoW fan so I'm personally used to big walls of text but I understand that its not to everyone's taste,. With that I'm looking to reduce the amount of text in the longer quests.
Casual mode is basically a very minimal quest version of the game. Its meant for people that just want to click and upgrade and don't really want a story line or loads of quests to do. Will be a while before casual mode is ready.
If you click the top bar you can switch between 4 different save slots
