Love the idea but the execution is really strange to me. Already joking around, talking and meeting people one day after you long-term partner's death took me right out of the emersion.
Choices are often pretty much the same just worded differently, this was very obvious when you ask Travis/Tracee if they are okay with being at your place. 6 answers that are all a variant of "I don't (really) believe you", not even one that's just "okay then" or anything along those lines. We are a grieving person who just lost their partner, all of the light-heartedness, joking, and banter feels extremely cold to me, like Elias/Ellie meant nothing to us.
Maybe you wanted it that way to make it easier for the player, I just wish you would have at least one route that lets the player actually grief and the writing reflect that.
