First of all, congrats on releasing your VN!
I didn't quite know what to expect going in. Not going to lie, this is probably the first time I thought a thumbnail looked funny: the title "All I need is you" juxtaposed with the shape of a meteor threatening to wipe out all life on Earth was hilarious to me. I wasn't quite sure if this was intentional or not.
Then the story begins and we are greeted by the president announcing he had blown up the moon, bringing about the apocalypse on Earth... I hope I don't sound disrespectful when I say this is probably going to be one of the highlights of the jam for me!
Unfortunately the rest of the story wasn't quite able to match the energy of the crazy opening and went for a serious tone instead. This isn't bad choice per se, but I am afraid the rest of the story remained a bit too abstract for the emotional stakes to work. We aren't shown specific memories or event, instead we are treated with the narrative and the characters just stating and repeating over and over how much they love each other. This doesn't have the same emotional weight and the single concrete element we are given (the wedding venue) isn't strong enough to compensate for the lack of details. And the story seems to be in a rush to end instead of establishing a mood: for example, the protagonist goes looking for his partner and they find each other immediately, the first car he happens to bump into happens to be his partner's.
In terms of presentation, even though you just used the jam sprites and some generic backgrounds, I thought you did a fine job with the tools at your disposal!
Overall, I don't know if this is what you were going for, but if nothing else I had fun with the premise of the story. I hope you continue working on your skills!
