Suggestions for the game: Allow splitting of items in your inventory. Allow holding ctrl or shift when buying items to buy multiples, allow gear sets so you can quickly switch between your normal gear and your XP/Gold gear.
Also make it auto-collect the drops, it's stupid that we have to manually collect the drops, especially because half the time it's too laggy to collect them.
Laggy and due to the fact you have to buy the bucks it takes forever to progress in the game. Very few are going to buy your bucks, and even fewer are going to play this game if all you do is make it so you need to buy them.
