The writing in this game is top-notch and gf and I were giggling a lot while playing, well done! Character sprites are also really cute.
The gameplay itself was a bit underwhelming though, even ignoring the visual glitches. I think even small changes could add a lot here, like having an influence on how long the dice is shaken. It can still be totally random (are the outcomes even random or did you hard-code them?), but at least make the player *feel* like they have some sort of decision to make.
Anyway, definitely worth checking out! At least if you think of it more as a visual novel than a game.
