This game is beautiful, please I need to know what the hell W is. I've been on this game for months.

Edit: Thank you. My life is complete.

FIRST TO 26 !!! I AM A WORD WIZARD !!!

lmao XD funni game
i got up to 14 but what is o??
okay okay what about u?
please have mercy on me... i've been trying so hard to figure out this mystery... hours of research... even a hint would be fine for me. why do i feel the compelling need to be the first to finish this game and see the end?
11/17/2021 damn it i came back and now i forget what m is. i knew this would happen. i always forgot m but refused to write it down for some reason.
2/28/2022
i am finally back. after a few days of long, hard thinking, i remembered what m was. i am stuck on r at the moment. hopefully it won't take as long to remember as m.
i just remembered r after writing this. i'm in the homestretch now, i am so close.
3/1/2022
i already forgot what r was, damn it. and now i'm stuck on u again. i can't believe i forgot that i still have to figure out u. i thought someone posted it in the comments. this is agonizing.
WHAT I JUST FIGURED OUT U IT WAS REALLY THAT EASY
i am at school right now, and i am at z. i will wait until i get home to finish and upload my score.
