Something a lot of people don't seem to realize: you can move your gold chest. This allows you to make your dungeon much more difficult to easily beat.
I love the idea because it brings be back to playing my psp but I really hope the devs optimizes it. My main concerns are the touch response and the heating of phone
Just touch and hold on the chest and you can move it to an entirely different room. Since reaching the chest gives an automatic 1 star, placing it in a far room gives a much better chance of preventing a successful raid.
