I think it would be awesome if there were, like, stuff that temporarily increases your gold gain per killed monster or your chances to do critical clicks or maybe something which boosts your Damage per second. Or your clicking power. Of course not unlimited. Maybe there would be a way to collect items which grant you to do it. Or maybe there could be some kind of mission-like thingy which pops up every day. If you complete it, you can get a jewel chest every four, maximum seven days. Or something like a social network where people could share their strategies.

Cheat codes would ruin the game. This is a long term Idle game, like IOURPG.
