I have no idea what game to do so post your day 4 unity game and I might just add on to it
That would be a different jam design, though a good idea for sure. A custom signup sheet could work, but requires a lot of guaranteed commitment of jammers. The % of joined to submissions is sometimes as low as 10-20%. Imagine 4/5 of assigned days being "no shows", it just wouldn't work.
They knew games would branch multiple times (perhaps a lot, perhaps so much that the last day is just two or three base games all branched out).
They knew games would die off. This part hurts a bit for projects that were actually good, so I feel like a "revival" opportunity or a "recovery" day might work for future jams to address this. Like a "Dead Pool" of strong projects that were not continued, that could be continued on any future day (with the downside of being down a day of development)
maybe you're right... though something that I thought might have been interesting is if the games worked on were ambiguous. That's part of the fun in the original pass the game challenge series--seeing what a average game can turn into within a matter of hours. This is what I tried with Budget Doom.
Here is a beautiful one: Budget Doom "Blood'n Gore" by IggyWise (itch.io)
project could use lots of little minor tweaks (and major level designs), and is missing a few key features of the "snow" theme (won't mention specifics)

Made with Unity (2022.3.0f1) for Day 4, where you play as a bus driver trying to escape the policemen and delivering people to there bus stop, have noice art for UI and character, nav mesh, written with some good clean code for the next developer, just need a way point system and models for buildings.

Take a look at my day 4 submission: Phantom Traverse Day 4 [Unity URP] by TinyRambutan (itch.io)
The enemies need a little love. I hope to see this game last until day 6. Really glad if someone can continue the game.
I made a cool tower defence game where you place animals to stop predators and humans ruining nature. You must go up against foxes, humans, and even an entire plough. Some work is needed but it would be perfect for Day 5. It can be found here.
The image is quite low resolution but the actual game looks even better. Please let me know if you check it out.
