God where do I begin
I guess i could start with the few things I wasn't fond of, as the game focuses on those aspects of itself primarily too. I found certain segments dull and monotonous to struggle through between the slow walk speed and a lack of obvious direction forward, but I would probably guess those aspects were on purpose to deliberately drive that specific mood home. So I guess this isn't even a critique, Oh No! My true form revealed: a fan!
I loved how you used color to contrast the dullness of the waking world vs the splendors/horrors of the dreaming world, not to mention segments where it was hard to tell if what was being witnessed was even a dream at all. Is Ollie a real person? Did the two of them actually meet? Questions without answers. Speaking of color, I was often floored by the fantastical shades thrown about, especially the sunset scene. The atmosphere had me on the edge of my seat in misery and terror, the three strongest scenes that affected me were: children's book, hot chocolate, arcade machine (kept nondescript for spoiler-free enjoyment). I was also legit impressed by the computer scene, specifically the mspaint gadget. That cant have been easy to code... unless it was... in which case still good job!
wait, I lied, one last critique... why must you prevent me from seeing my boys just hug, or hold hands for a brief moment ;n; they both deserve happiness.
