The expectation of a roguelike is that control will be primarily via the keyboard and only perhaps supported with the mouse, if at all. Ardanteia is primarily mouse based which is the opposite of expectations. I think it would be prudent to fully implement keyboard support so its available.
This shouldn't be too hard, all of the input is there, just need to work out how to handle things like using an item from the inventory etc
The game can be effectively controlled using the keyboard
Items can be used
