Creator tools
Control publication, update the game page, and test how the playable build fits.
Publication
Public profile
Cover art
Leave blank to keep the generated synthwave scene. PNG, JPG, or GIF.
Playable surface
Use dimensions from your real canvas or exported game viewport.
Display fit
Test different devices, then save the fit that looks right.
Best for fixed-resolution games. Needs a game width and height above; the game scales down to fit any screen, never cropped.
Play guide
Overrides the guide text the build sends. Leave blank to use the build's own copy.
Links
Save profile, playable URL, links, and viewport metadata.
