Not bad. It was a headline game for last month's Humble Monthly, so that's a good 'get' for Epic. Unfortunate for anyone still subscribed to the Humble Monthly, but their deals have been getting much worse ever since IGN acquired them.
The game itself is a fairly laid-back experience, but kind of slow and repetitive. I don't plan on finishing it, but it doesn't really seem to go anywhere after the first dungeon.
