Certain resources like the costume gems are really hard to get! If you added them as daily rewards it'd be better. Edit: I have an issue with this game. Sometimes when I finish a battle (in any mode), it will have a connection error. Then I have to close the app and reopen. When I come back, it let's me go back to that battle but I automatically lose. Why does it automatically fail you? Edit: Game freezes sometimes when I enter a battle in The Sweet Tower of Chaos. At least I get my keys back?
