1. Identify the version before applying a fix

The full game launched on Steam for Windows and on Android. The developer’s itch.io page still labels its HTML5 version a demo. The browser demo’s current build has not been verified here, so a full-game patch note cannot automatically diagnose it.

Choose Steam Windows, Android app or itch.io demo; check the version and symptom; contact official support if the issue persists
Site-created decision diagram summarizing the version check; it is not a game screenshot or a live service test.

Write down the platform, installed version if visible, the account used and the precise symptom. If you changed accounts on the same device, mention that detail before taking further save-related action.

2. Match the symptom to the developer’s stated fix

The dates below distinguish a reported fix from a current diagnosis. They do not establish that a past run or profile can be recovered.

Your symptomDeveloper noteWhat it tells you
Extended Mode finds no opponent or fights a copy of your own teamSeptember 19 hotfix 1.0.3 listed these cases as fixed.Check your full-game version; a fresh occurrence still needs reporting.
Progress or run save appears under the wrong account after switching accounts on one device1.0.3 and September 21 patch 1.1.0 describe related account-switching save fixes.Do not assume missing historical data was restored. Record both account context and version for support.
Android sign-in returns from a browser but does not complete1.0.2, 1.0.3 and 1.1.0 each list specific Android sign-in fixes.Check the installed app version and report the exact return or timeout behavior if it persists.
Controller cannot dismiss “Progress Not Saved”Patch 1.1.0 lists this controller popup fix.Check whether the installed full game includes that patch; do not treat every save warning as this bug.
Extended Mode resumes to a black screen with a very large trinket bagPatch 1.1.0 lists this specific fix.Report a continuing case with the mode and symptom; do not infer a general loading fix.
Browser demo stays on “searching for opponent”An itch.io player comment reports this, but the demo’s current build and live service state are unverified here.Do not assume the full-game hotfix applies to the older browser demo.

These distinctions come from berrymint’s dated Steam updates (opens an external site). The browser report is a player comment on the developer’s itch.io page (opens an external site), not a confirmed fix or universal fault.

3. If it still happens, use official support

Keep the report specific: platform, installed version, account-switching context if relevant, what you expected, what happened, and when. Avoid emailing passwords, payment details or a save file unless official support specifically requests one through a trusted channel.

Protect an affected save

The public notes do not provide a verified recovery procedure for lost progress. Do not delete local data, clear browser storage or repeatedly change accounts on this site’s advice.

Steam’s Batomon Showdown technical support page (opens an external site) identifies the developer support address. The same address appears in the Google Play listing’s App support section: berrymintdev@gmail.com. This is the game developer’s contact, separate from this fan site’s corrections address.
