I was just making mention that I love this game on Steam, but that after paying $5 for it there, paying $5 again on Windows Phone was a bit too steep for my liking. Then, I saw on Store Deals just now that it's on-sale for $3, so I'm jumping on that, and I thought I'd give others a heads-up about it.
