§1

The scope balance sheet

21 rows

On 14 July 2026 the developers posted the full 1.0 content list against the demo build players had already tried at Next Fest. It groups into seven areas — Threats, World, Progression, Outpost, Loot, Balance and Platform — with three to four additions each except Balance, which carries the single line the whole demo feedback thread was asking for. Filter by area below, and switch which build reads first with the radio pair; the sheet re-labels its own columns rather than just re-sorting the rows.

Three areas carry the most consequential rows for a returning demo player. Threats adds a boss encounter and elite encounters on top of new enemies, none named. World adds two biomes with dedicated ambience music and new elevator modifiers, which change what a run looks like before the doors even open. Outpost adds a second floor, new NPCs, more constructs and the enchantment and repair machine — four of the twenty-one rows in one area, the largest single share on the sheet. Loot, by contrast, is a smaller but still real expansion: legendary gachas, many new items and many new hats, none of which existed at the June demo's gacha tier.

§2

What the demo actually was

12–22 June 2026

The public demo went live on 12 June 2026 at 10 AM PST and ran to the end of Steam Next Fest on 22 June; every earlier playtest key was deactivated an hour before it opened. It passed 350,000 downloads and placed in the top 15 most played games of the event, which is where the wishlist curve came from — 20,000 in the first three days of June, 100,000 by 20 June, 250,000 by 28 July.

It also produced the one piece of feedback the developers answered in public: difficulty. The 20 June post carried a developer note about it, and "difficulty balancing" is on the 1.0 list as the sole Balance-category row in the sheet above. Official updates holds the dated record of every post between that note and launch day, including the two limited-time events that followed it.

The announcement trailer embedded below predates the 350,000-download figure: it is the pre-launch pitch published alongside the 14 July scope list, filmed before the studio knew the final wishlist count or the Next Fest placing. Watching it next to the balance sheet above is the fastest way to see which lines were promises and which had already shipped in the demo build by the time the trailer went out.

The gap between the trailer's publication and launch day is also the entire window Official updates tracks in the Balance category: difficulty balancing is the only 1.0 addition filed there, and it exists specifically because of feedback logged during those eleven demo days rather than because of a plan the developers had before Next Fest started.
