Definitely a very interesting setup for a game, a bit limiting but obviously 48 hours not that much to be able to make. But an interesting concept none the less that reminds me of a few similar games I have played. Though it leans somewhat into the weirdness of the dialogue, but there's now ay to see the true dialog which is unfortunate.
I feel like some sort of randomization between some quotes on the different dies and such could be interesting. That way it would pick a word or a sentence or something. And then go from there to just make it completely weird. Even if it doesn't fit at all.
Definitely an interesting experience though for sure. I'd be interested to see more situations and such with a setup like this.
