I must premise this by saying this is very impressive as a jam entry made by a one-person team. The art is plentiful and lovely, the lighting and the use of color used for the backgrounds to highlight the most dramatic moments is especially striking.
Above all, I love the experimentation of having different section focused on visual and auditory experiences. It's a very interesting idea and I like how the story does a lot with that concept in general, of the characters being able to perceive different things. The highlight for me was the scene in the bar, where the inability to see or hear is used a lot to hide some information from one character or the other.
I don't think there's much more than could have been accomplished within the constraints of the game jam, but I would like to see the presentation pushed even further. One thing that I felt that was missing is that the "blind sections" ended up feeling a bit too silent for me, in terms of diegetic sounds. I know it's asking a lot, but having some voice-acting for those sections would really highlight the difference. As it is right now, the dialogue in particular ends up feeling very same-y regardless of whose perspective we are in. (This isn't helped by the magic technology introduced in the story. While I understand the need to have something to facilitate the two characters interacting, I think something a bit more grounded than what essentially amounts to telepathy would have fit the story better.)
The story explores a lot both narratively and with its presentation and was in general a joy to read. I must admit though I had a big issue with the story itself: I found its overreliance on melodrama and tragedy a bit tiring. There is too much going on, which hurts the pacing and doesn't allow us enough time to process each sad backstory element because we got to move on to the next one. The whole story seems to be build so that we can experience a sense of catharsis by the final scene, but that didn't really happen for me. In fact, by the final scene, instead of trying to sublimate what we have accumulated so far (which is a lot) the characters introduce even more sad backstory elements! For a short story such as this, I think we would have needed more streamlining.
One final element that I would have liked to see explored and developed a bit more is what exactly kicked off this relationship in the first place. On one hand, we have the deaf guy stumbling into a complete stranger on his way to his girlfriend's funeral and deciding to invite him to a gay date even though he has zero clue about his sexuality... Which is pretty wild already on its face, but again, funerals are usually held within a few days after someone dies, and the way the protagonist acts doesn't seem like the way someone would act when your significant other's corpse is barely even cold.
On the other hand, the blind guy is stripped of much of his agency in the romance because his personal circumstances (he has no friends, no jobs, no perspectives...), so the answer to why he's attracted to the otter seems to be he's receptive to someone finally paying attention to him. Not a problem per se, but the story seemingly equates this character's personal circumstances with him being blind. As someone who has dated a blind guy, I would have enjoyed the relationship being a bit more driven equally by both characters.
Having said all that, I reiterate this was a very enjoyable and interesting read, and a very impressive entry.
