Finished Contrast on PS4. Short, VERY interesting mechanics, unique graphics, very good story and characters but it is let down by poor gameplay. It has terrible collision detection, an unpredictable camera and sub-par controls, making what should have been a fun game a bit frustrating at times. Pretty sure that's why it was free.
Trying to beat Resogun on Veteran and not having an easy time of it, but still enjoying it as an extremely fun time waster. Downloaded Tiny Brains demo last night and tried it out, not too shabby, but not great so far.
Also tried TRINE 2 last night and holy moly it has some amazing graphics and is even more impressive in 3D with eye popping backgrounds for a sidescroller. Reviews say it isn't a solid one though, so I may wait to see if the price drops.
