A nice polished typing game.
The first time I played I definitely missed some mechanics, so I wonder if the explanation page should go before the game play rather than after you lose. But I can see the appeal of throwing the player into the action. But before I saw it I assumed you had to type the last word in the chain, rather than any word, and didn't realize you can get rid of words by making color chains.
I think the use of the limitation might be a little weak. It almost feels like while playing you are destroying the bad thoughts not injecting them. The text outside of the game says I am injecting bad thoughts to control the game but when I play it I type them and the pop like I destroyed them. Combine that with the upbeat music and it feels like a game about overcoming your negative feelings, rather than brainwashing someone.
Overall an enjoyable jam entry.
