I spent the last evening trying to finish Affordable Space Adventures on the WiiU because I heard the ending had a Miiverse connection. Started too late so didn't make it under the wire (about half-hour too late) so didn't get to post in Miiverse but Affordable Space Adventures is a really great puzzle game that uses the gamepad in a good way.
Had no idea what Affordable Space Adventures was about or what type of game it was (got it with the Nintendo Humble Bundle some time ago and never even started a file) but I really liked the whole package and thought it was a quality hidden gem and the Miiverse part was neat too.
