Funny how I just end up counting fingers in those games... (and well, it's always uncanny, in those you pretty much never have thumbs but still have at least five fingers)
It could be a bit tricky to edit but as most of the time you'll have to just remove one it should be doable with the tips above.
Also typo-wise I would say it should be more like this :
that lets him match with Lena and sucks him into a strange Velour Room where he discovers his ability to wield strange powers and visit worlds formed from the inner consciousness and reality of the people he matches with
(I also think it's a bit too heavy, that's a personal view but I would find :
"that let him match with Lena then suck him into a weird Velour Room. There he'll discovers his ability to wield strange powers and visit worlds formed from the inner consciousness of the peoples he matches with"
would be a bit better.
-"and" become "then" because it sound more possible to first match then getting sucked in.
-I decided that the room is weird because later the powers are strange, too many strange things could get stranger so ... Yeah ... But the powers could be supernatural, just powers, marvelous, amazing, interesting, useful and so on...
-A little bit of punctuation help breathing, but "where" would sound like a question so we'll go with "there".
-We'll also use "he'll" because at the point where the player is it didn't happened, but it will.
-I removed "reality" because it just add words while sounding way too deep. Let's imagine there is just one reality and multiples consciousness only, multiples realties feel like a handful.
