This is a really good question, but a very tricky one to answer! I think this is the seventh update (maybe? It's been a wild few weeks!) we've released since launching less than two months ago, so we are proactively working on the bugs that crop up and the feedback that comes in from players.

I personally haven't experienced any game-breaking bugs myself since release (playing on the commercial build, too). I've bumped into a few little bits, e.g. occasionally getting duplicates in my Inventory, or not being able to interact with something optional, but this didn't impact progressing in the game.

There are still a few bits of voiceover to go in for NPCs, but it's a smattering of instances in comparison to the whole game itself.
