I just played it! For the first time I managed to get all endings with my own effort huhu ಥ_ಥ The illustrations are really lovely; I truly enjoy seeing such style! And although the game play managed to be done quickly by me, it was really good for your first game! (Who am I to comment much when I have never done my own other than just writing stories ＞﹏＜)
If I may suggest though, perhaps in your next game you could add an ending section so that players can keep track of the endings that they have achieved? :o There were only 3 endings for this, so it was manageable to keep a track on >< but if you were to have more than that, it would be slightly harder I suppose ;; Nevertheless, congrats on such a wonderful first game! <3
