Definitely get a lot of nostalgia with this game, really made me want to explore. I don't know if it was just whatever random seed I got though but I did not find anything after exploring for quite sometime. The locals told me about an infested vault and that it was near a broken tower but no matter how far I walked or looked, I never found a broken tower with any entrance. The movement speed was also brutal for how large the world is. A faster default or some sort of sprint mechanic would go a long way.
As it is, I like the potential and the idea here, but there wasn't much gameplay that I found. If the issue is that the seed can have a wide range of first experiences, maybe a default seed that you know turns out well should be inputted by default. So that way most first impressions are typical and players can change the seed to have a different experience. I think you've got a great base here, just needs more content and polish. As with the previous poster too, the NPCs were definitely weird as is. Even if you don't add movement, they should at minimum not all be facing the same direction.
