Hey Zorch, thanks for playing.
Maybe I just have an unusually large monitor here, I suppose it is pretty large. None the less, I've just gone through and refactored all the UI for 1440x900 resolution and re-uploaded it. I zoomed the camera out a bit as well, since with a screen that small it felt a bit too zoomed in.
Very peculiar about the crashing during combat. Had you switched around the gear at all? I haven't locked down the equipment slots yet, so I could imagine if you equipped a weapon as armour, or armour as a shield, something could go awry. The icons in the top row may not be very clear I suppose. The first row is Weapon - Shield/Torch - Armour.
Thanks for the feedback on the movement. I've got the default move command working as an "Attack Move" command, but perhaps it would be better to move that to a hotkey as seen in games like Starcraft.
