One recommendation I could make, and I hope my comment doesn't get lost in the sea of comments, is to allow the use of custom characters. Being able to create our own characters to enter the dungeons, incorporating what we love about the game, would provide an incentive for artists and increase replayability over time.
It's quite tedious, I won't deny it, but if you think about it, you'd be missing out on a great opportunity for your game if you didn't consider the idea. There will always be people who dedicate their time to doing this kind of thing. Leave that possibility open for players to use custom characters. I always say that games live a little longer when they give players the possibility of using mods, or in this case, custom characters.
