[2022] Valheim finished in 4 years(?)

That means to me the game is currently at 20%.

Sorry to say, but this is completely wrong. Version e.g. 0.203.13 doesn't mean the game is 20% done, please visit https://semver.org/ to learn about Semantic Versioning (Edit: I should add that Iron Gate doesn't 100% use Semantic Versioning as described on the website, but it's pretty similar. Just wanted that you get a feeling of how versioning software works, it's not that easy.)

On EA release (Feb 2021) the game was feature-wise about 75% and content-wise about 50% complete.

No worries!
