Overview
PCGamingWiki lists ultrawide resolutions as supported for this low-res (480x272 native) pixel-art game, and no fix is needed. How the HUD, menus and the Theora intro/ending videos look at 21:9 or 32:9 is not documented, so those fields are set conservatively.

Patch history & verification
Current Steam build (number not confirmed)Oct 17, 2026
Verified PCGamingWiki ultrawidescreen=true; no Flawless Widescreen module. Only one solid source; HUD/menu/cutscene fields are conservative defaults, not confirmed - rated good rather than excellent because of that uncertainty.
