Just played this on my GBA using a flash cart. Very enjoyable little game. Closer to a visual novel than a game imo, but still very cute and fun.
My only complaint would be the cleaning mechanic. Pressing the action button when coming across cobweb would have been more enjoyable if it either brought up a minigame to clean it, or just made it disappear. The dialogue box asking if you want to clean it felt a bit clunky, and by the end of the game felt like it drug the game out without making it more fun.
Aside from that, I loved the game. I haven't completed both (or all?) endings, but I did the good one and I could see where the choices split. Oh, the music! So good! Artwork was a plus as well!
