Okay, feedback time. First: It would be nice to have new blocks, or at least we could pick the color and it's function. The only floating block is pink, and it doesn't looks really nice with almost... anything. Also, a menu with simple instructions. I mean, sometimes it takes a few seconds to realize you can click the screen and press enter, instead of just keep walking around. And finally, online-users list. Nice idea, but can be improved a lot.
To EVERYONE complaining about your army not going to the second floor, read the announcement that says: "Warning! NO GOLD COINS on this floor! Adventurers will not go to the next floor!". That means you need to buy the next floor and then put at least one of those "money bags" on your dungeon's ground. Hope this helps.
