Glad it runs, and that's a genuinely useful writeup, thank you.
On the reporting thing, since you mention it: your crash report is the reason there are downloads on the page at all. There were none before you posted, my initial take was browser build or nothing. So it didn't go into a pit. It's why you were able to check it out tonight, and why the next person whose browser chokes has somewhere to go instead of a stack trace. Worth knowing before you decide the reports aren't landing anywhere. For what it's worth, I have a similar experience in reporting bugs/issues - and if my opinion matters to you - keep doing it as long as it doesn't cost you too much energy.
You're right about the card, too. The Third Eye cuts your maximum sanity rather than draining it, and nothing on screen tells you which of those just happened - the bar gets shorter and you reasonably assume something's eating it. That's the second time a card's wording has made a mechanic look broken, so it's going on the list as a pattern rather than a one-off.
The blunt read on the premise is more useful than a polite one would have been, so thanks for that as well.
Six minutes with a cultist finishing you off is around the middle of what I've seen, for whatever that's worth, you're not the outlier you think you are.
