Editorial Policy: How This Manual Handles Numbers
The about page says where this site's numbers come from. This page is the operating manual behind that promise: the rules a page must pass before it goes up, and what happens when one turns out to be wrong.
Rule one: no orphan numbers
A figure may enter a page only from one of three doors — Steam's public APIs, a Steam guide with a named author and posting date, or Mumpitz Games' own published text. Each page's frontmatter lists exactly which doors it used. A statistic that arrives without a source attached — from a forum comment, a video thumbnail, another wiki — waits outside until someone traces it. Most never get in, and the pages say so in their "what is missing" sections.
Rule two: the retrieval date travels with the fact
Steam unlock percentages shift daily; review scores drift; patches rebalance turrets. So a claim like "the four-type achievement sits at 12.1%" is incomplete on this site — it has to read "12.1% as of 1 September 2026." When you see an undated number on a page here, that is a defect worth reporting, exactly like a broken link.
Rule three: disagreements get printed
When the itsuno guide and another player's write-up give different routes to the same achievement, both appear with attribution. When no source can settle a question — total level count, upgrade-tree pricing — the page states the question is open. Choosing the more confident-sounding answer is how wrong numbers spread; this site would rather look uncertain than be wrong.
Corrections
When the live game contradicts a page, the page changes and its updated date moves. If the old claim could have cost a reader real effort — a wrong achievement route, a wrong requirement — the correction is noted in the text rather than silently overwritten. Reports arrive through the contact page; ones that include a screenshot or a source link jump the queue.
Money and content do not meet
The site is funded by display advertising served by an external network. That network chooses the ads; we choose the words. No advertiser sees a page before publication, no ad placement is sold against specific content, and no affiliate consideration shapes whether we call the Supporter Pack worth buying (our page on it simply lists what Mumpitz Games says it contains). If the funding model ever changes, this page changes first.
Who writes this
One person who owns the game, plays it, and reads the community's guides closely enough to notice when they disagree. No AI-generated stat tables, no outsourced filler — the site is small precisely because everything on it had to clear the rules above.
