It's not just "artsy" though. Eden has great controls. It has terrific gameplay. If it were less "artsy" and more conventional graphically and musically, people would realize that it's a really hardcore, almost oldschool platformer. I love the way it uses a few basic controls and gameplay elements, yet those basic controls and elements really reward the player that really masters them. By the time you finish the game with all Spectra, you can really fly almost effortlessly around the levels because the controls become so intuitive.
Pixeljunk Monsters (better than Eden)

PIYOTAMA - I founded the defense force, if you like puzzle games u should love it. Plus, it's only 2.99
Leaves you with 6 bucks towards Crash Commando or Calling all Cars or a future game if you want. I'm tellin ya, PIYOTAMA!!!
I don't like most tower defense games but I love pjm. I think it's all about running around as the little dude, plus it looks incredibly sharp on 50" 1080p
