It really rubs me the wrong way that the video uses the word "fixing", as if the blur is something that is broken or unintended. It seems really disrespectful to a deliberate artistic choice. I totally get not agreeing with a choice like that, but to make art and then have someone say "Oh I can fix that" just seems like a shitty thing to do (I'm probably just a bit sensitive to this as I work in an art field, so perhaps this is irrational).
But I will say... I love the visual choices for this game. The art style is gorgeous and I really dig on the tilt shift style. Not to mention that the soft edges create a natural focal point for your eyes in the center of the screen (although, the original game wasn't designed around this and had a sectioned off map, so perhaps this would be more useful in a different game that took the blue into consideration).
If this game held a solid 60fps then I'd give it a 10/10. But that slow down is just so brutal. I would've rather had a sectioned map if it meant no frame drops.
