We've known the well-received XBLA title was headed for the PC since March, though it didn't quite scrape into its predicted April release window. Not a big deal, really, seeing as it's available now on Steam with a discount of 10 per cent until June 1.
If you purchase it before the aforementioned date, you'll only have to spend $US13.49, rather than $US14.99, to own the title. There's no rush and it's certainly not the chunkiest of discounts, but it's still cheaper than its console-bound counterpart.
The PC version comes with support for both the Xbox 360 controller and Steam's "Big Picture" mode, so you'll be able to play it exactly as its creator's intended, though I'm sure you can manage with a keyboard and a regular-sized picture, if you so choose.
