Steam Deck compatibility
Valve has not rated it: resolved_category is 0 as of 14 November 2026. The store description mentions Deck touchscreen controls; a Linux outlet reported support.
Steam Deck support for this game is a two-source question, and the two sources disagree. Valve's compatibility API returns the game as unrated. A Linux outlet reported, on the back of the announcement, that the game arrives with Steam Deck support. Both statements are true as of 14 November 2026, and they are not saying the same thing.
Two claims, two sources
| Source | What it says | What it means |
|---|---|---|
| Valve compatibility API (app 3384600) | resolved_category 0 | No rating yet; untested or unreviewed |
| GamingOnLinux, via Steam news | "arrives December 9 with Steam Deck support" | The outlet reports support; Valve has not rated it |
| Steam store description | "Steam Deck™ supports touchscreen controls" | A claim about input, published by the publisher |
The rating scale Valve uses runs from 0 (unknown) through 1 (unsupported), 2 (playable) and 3 (verified). A zero means the review has not happened. It does not mean the game fails.
Checking the rating
- Open
store.steampowered.com/app/3384600/. - Look for the Steam Deck compatibility row on the right-hand column, under the purchase box. It shows one of four states, or nothing if unrated.
- For the raw answer, request the store's own compatibility endpoint -
saleaction/ajaxgetdeckappcompatibilityreport?nAppID=3384600on store.steampowered.com - and readresolved_category. Zero means unrated.
That endpoint is the same one the store uses. The closest thing to an official answer, and it currently says nothing has been decided.
Reading the touchscreen line
The store description's Deck line is narrower than it looks. It confirms the game has touch input on Deck - which matters for a puzzle game built around stylus-style interaction - and says nothing about frame rate, text size, controller glyphs or suspend behaviour. Those are the four things Valve's review checks.
For a Layton game those four matter more than usual. The DS entries were built around a stylus, so touch is the natural fit; the question is whether the puzzle screens are legible on an 800p screen and whether the interface switches to controller prompts when you dock it.
Why the report holds up
Two things support it. The publisher advertises full controller support and Steam Input API support, both of which are prerequisites for a comfortable Deck experience. And the game is a puzzle adventure, not a rendering showcase - the kind of title that usually lands at Playable at minimum.
Neither is a rating. Buying specifically for Deck leaves the honest position at this: the publisher says touch works, an outlet says support is there, Valve has not signed off.
Deciding with it
| Your situation | Reasonable move |
|---|---|
| Deck is your only PC | Wishlist now, buy after the rating appears |
| Deck is a secondary device | Buy on Steam; the desktop version is unaffected |
| You want Verified specifically | Wait for the badge; no date is promised |
| You need HDR | The store lists HDR available, so check the Deck's own HDR support separately |
Valve typically rates games close to release, so a badge is likely before 9 December rather than after. A pattern, not an announcement.
