In today's Nindies Showcase three titles were bundled together to emphasize their support of HD Rumble; one of them is coming rather soon, too. Mr. Shifty - developed by Team Shift and published by tinyBuild - is an intense top-down action game, with the HD Rumble designed to allow you to "feel every punch, shot and crash".
The character can shift through space, as the name suggests, and it looks rather fun. Oddly, this writer can't get Die Hard on the NES out of his head when watching the trailer, albeit Mr. Shifty will likely be a lot better.
It looks pretty tasty and is out in April, so not long to wait.
