Wow, this game is amazing! First the twist, then the game seeming to get all Doki Doki Literature Club, only for it to thankfully not go that route and do its own thing! Very well done!!

For those who want to know how to get Ending #3/the secret ending, when you get to the one place in the game where you're presented with a choice, say no. DO NOT SAY YES. Otherwise, you'll have to reset your progress. Thankfully, once you get the secret ending, you can proceed as normal and get the rest of the endings.
