very cute with a lot of potential, i'm assuming you didn't have time to program specific words into the game but kinda made it better since i could tell the bad thoughts "ok boomer" or "no u" or even "poopoo" and it worked, if you plan on programming specific words i'd say don't limit it too much, the words should be somewhat words but typing "no u" to a bad thought gave the game a nice comedy tone of sorts. also, i saw other games do this but switching between mouse and keyboard is frustrating usually unless you give the game a slow enough pace. i would suggest changing the controls of the words for mouse to wasd while keeping the character idle or something.
