This is a fantastic game, and one of my favourites played so far. I loved the central mechanic, I loved the funny writing, and I loved the style of it. So much of it worked so well, and I can see this growing if you wanted to take it further. The core mechanic works so well, it could definitely be expanded.
I have three points of feedback, but please note how minor this feedback is, and appreciate how much I loved the game. This is simply little, easy-to-fix coding suggestions.
1) It felt a little weird to play the game primarily with a mouse, but then have to press space. This could be a mouse click instead.
2) I would have the first button press during dialogue fill the rest of the dialogue, and the next button skip. I unfortunately skipped past a few bits of dialogue
3) The dice tend to scatter outwards, which means that often the numbers show right at the edge of the screen. I would have some kinda invisible wall come in to effect to keep the dice somewhat centralized.
But, as mentioned, these are super minor points in a game that is genuinely brilliant. Fantastic work!
