I love the base mechanic of the game, but the amount of controls needed are a bit difficult and unintuitive, for instance having shift and enter to repair the magic means I need to use the mouse hand, which I'm using for attacking.
The most glaring issue I find with the game is that there's no reward for playing. No progress bars or flashy "You've been promoted" or kill counts, which makes it hard to want to fight off the monsters.
Love the graphics though, and as I said the mechanic itself of repairing your movement ability is really nice.
