This is just incredible. The potential nuance of this system is just amazing and it was really fun to play and the excitement of knowing there were more powers to go learn and try out was really cool and really nails the feeling of knowledge is power which is sounds like is exactly what you were going for.
My favorite strategy was to spam "HHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH" and then when i was in trouble i could just add a "OT"
I also cannot believe you made it so players type the menu options and that they still work even when you are not in the menu and just playing the game. That is such a fun little gimmick and I'm so impressed you didnt have any issues with words typing into eachother (like hot into hotdog) since the typer automatically sends words once it detects one. And making left shift a speed boost was just amazing 10/10!
