Fun little game! I don't personally like visual novels, but I ADORE the visuals!! I love the artstyle and formatting!! I'm not sure if this exactly counts as a game, I'd recommend using Ren'Py for your future visual novels, cause you can add sound, and stuff. I didn't have much time to play this, but I like what I saw.
Nice work!! But again, Ren'Py could be way better than Google Slides, if you wanna do something larger, or just better.
