I have a suggestion for Grinnfinite Dungeon: If u place the "next room"-button a little more left, the player haven't to wait for all the loot-loading. In this way u (players) can raid the dungeon faster and have hopefully more fun.
Some new player seem to have a problem to get along with this game... there were suggestions about "game needs a repeat-tutorial-quests button" in the chat. Additionally (I don't know if it is in the tutorial) there should be explained what the "red !" stands for.
