I think it's cool to have many assets. Just that the assets have to be optimized for the jam. For example, i've added a bunch of computers to my game, and the build size went from 40mb to 170. But after selecting all textures, and setting them to max 256x256 resolution, it went back to 50, without any major visual differences.
I remember in the iphone 4 era, we has a budget of 150 draw calls and 200k polygons for the entire game. I bet that just hair on a high poly model will blow that out of the water. I see 'low poly' assets with 2 millions polys and 1000 draw calls.
that stuff really matters for performance and build size. Especially for the jams
