The title screen is fantastic.
Plays very well with the mouse interface.
One thing that I think would be really great would be some sort of quick throw command. A command that would automatically throw a dart, some sort of predesignated ammo, or that chooses the most likely item to be thrown.
Both as a keyboard command, and a mouse command button at the bottom. It gets a little annoying when using the mouse to click inventory, the darts, then throw, then the target when you want to throw several darts at an enemy. Being able to click a quick throw type command, then the target would be much smoother in my opinion.
