Guacamelee! Super Turbo Championship Edition (PS4)

Ether One (PS4)
This haunting, first-person puzzler tasks you with restoring the minds of the mentally ill by solving complex puzzles and sewing together the frayed strands of the patient’s lives. Be warned: not everything is as it seems.
The Unfinished Swan (PS4 | PS3 | PS Vita)
Developer Giant Sparrow made big waves with this project thanks to its astounding art style and thought-provoking gameplay. Will you help find a fitting end to this fairy tale? Experience a breath-taking story filled with delightful twists.
Race the Sun (PS4 | PS3 | PS Vita)
This minimalist racing game forces you to compete against the setting sun in what is both a deeply calming and nail-biting session. That may sound like a contradiction, but it’s true!
Hohokum (PS4 | PS3 | PS Vita)
A supremely relaxing game that’s bursting at the seams with personality. Explore a crazy, colorful world, meet new friends, and just let go as you listen to the incredible soundtrack by a collection of talented artists.
Murasaki Baby (PS Vita)
A strange puzzle game with an eerie atmosphere. Players guide Baby through a nightmarish landscape in search of home. It’s cute, and also a little weird.
I'm gonna try Guacamelee for sure.
