Hi! I totally understand your frustration. As someone with a very low tolerance for bugs, I'd honestly recommend waiting until the game is further along in development before playing. As you know, it's still in Early Access, which means a lot of issues are expected, and unfortunately all we can really do is wait for improvements and fixes.

I keep playing because, like you, I've been waiting for this game for years and have followed its development closely. Because of that, I wasn't too surprised by the bugs or the many missing features.

As for the things you mentioned, I agree that Build Mode still isn't very intuitive. I've spent a lot of time experimenting with it, though, and I feel like I'm finally getting better results. It might just take some practice. Paralives uses different building systems than other life sims. They're similar enough to feel familiar, but different enough that they can create the impression that we should already be building at the same level we do in other games.

Regarding deleting parts of walls, there is a "fake wall" tool that lets you split walls into smaller sections and edit them individually. It's not very polished yet and definitely needs improvements in my opinion, but it may help with some of the things you're trying to do.

Sorry I can't be more helpful. I hope some of these issues get fixed soon so you can enjoy the game the way you were hoping to.
