Cute and short game! I managed to get all 4 endings, but am unsure about how to reveal the secret. Is it possible, or is it just put there as a gag? If it is possible, I'd love a hint!
Ah! The reveal secret button is just there as a joke, its not possible to select it. It's a text swap of the "formation" button which is included in RPG Maker to be able to switch around the order of your party and is inaccessible because there is only one character in the game. I decided to put some cryptic text there for some fun, sorry about the confusion!
