Sound Shapes, partly developed by local developer Queasy Games, celebrated its third anniversary this past week and is doing so in a big way.

First, if you're not aware, the game is free this month with PlayStation Plus. After the the month, or if you're not a PS+ member, the game is on a permanently sale for $9.99, which gets you the game on PlayStation 3, PlayStation Vita, and PlayStation 4. There is also cloud saves, and separate trophy lists (triple platinum!).  The game's DLC is also half off for the rest of the month.

You can check out the PlayStation blog post to see some of the bonus albums by some developers and composers, as well as some tips on how to see the user generated content.  

Congrats to everyone involved! Make sure to follow the game on Twitter for all the updates.
