Which I think is like, one person here, there's a great deal on Locoroco: Midnight Carnival at the moment. It was £12, which is why I never bought it, but now you can get the full game, the DLC pack with 3 extra levels, and a strategy guide (digital copy of course), for about £5. Which about 8 or 9 euros I think?
Which is a damn good deal. That's 19 levels in total. Locoroco 2 only had 25 levels, and that was a full price UMD game.
