This game is currently on sale for 25% off… But due to being a pay what you want game—specifically with no minimum price—the sale has no impact on the cost of the product.
That aside, the fact it shows up in the sale listings is a bonus; more people need to see this. If I had money to toss at games I like, I'd toss some this way. What's here so far is great quality and entertainment, in my opinion.
