I know everyone has harped on this, but I wanted to put in my own two cents on the issue that's unfortunately overshadowed your review.
In the video you already mention that Ori comes from the highly decorated and beloved "Metroidvania" style of Platform Adventures, but then go on to compare Ori to games like Rayman, Donkey Kong Country, and Super Mario Bros.
It's like comparing Metroid Prime to Halo: Combat Evolved. Sure, they're both first person shooters, but one is a linear style game spaced by distinct and seperate levels (Rayman, Donkey Kong Country, and Super Mario Bros.) while the other offers an open world for you to explore while you gather new abilites to open previously inaccessable areas (Ori). There is some comparison to make with their core mechanics (in this case both Mario and Ori use their movement abilities to traverse the area to reach their goal), but the ways in which they achieve their goals varys considerably.
Games like Super Metroid, Casltevania: Symphony of the Night, Guacamelee, Shantae & the Pirate's Curse, Axiom Verge... these are the games that share the most similarities with Ori & the Blind Forest, and should ultimately be what Ori is compared to. I get that Ori is more platformer focused than the more action focused games like Metroid and Castlevania, but the core concept is still the same.
Sorry for beating a dead horse, but these two genres (Platformers and Platform Adventures/Metroidvanias) are some of my favorite of all time and their distinctions make them very unique genres from one another.
Speaking of Axiom Verge, I think it would be interesting if you did a compare/contrast with Ori. Both are Metroidvania styled games that have just come out to high praise and acclaim. I think it'd be interesting to see in what ways they're similar and how they're different... and in the end seeing how they compare to one another.
Finally, and kinda randomly, but you have a vocal tone that really lends itself for a spoken video style review. Keep it up!
