BOMBANANA Demo to launch, then Steam news

This page is the audit trail for BOMBANANA!, not a fake changelog. Lefto Studio has not published a public, numbered patch list for the full Steam build as of this writing. We will not invent 1.0.1 or hotfix #4 to look complete. If you need a version string, open the installed game’s Steam properties and compare it to the latest Steam news post for app 4656000.

What we can document is three layers: demo-era hotfixes that already hit Steam news, the demo-to-full feature jump that landed with the 2 September 2026 launch, and a repeatable way to verify whatever Lefto posts next. The launch notes stay the readable day-one list. This page stays skeptical.

Honest status: no public numbered full-game patches yet

Launch day is a content drop, not a patch-note dump. The studio’s “BOMBANANA! Is out NOW” post describes modes, environments, puzzles, the monkey overhaul, art direction, server browsing, room codes, controller support, Steam Deck mention, achievements, and colorblind options. It does not attach a semantic version. Until a later news item names a build, treat the live Steam depot as “the launch build” and do not argue about patch IDs in Discord.

This wiki tracks Lefto Studio and Steam announcements. Community wikis, Reddit, and TikTok are useful for “our trio died on this module,” not for “the game is on patch X.” If a creator overlays a version number that Steam does not show, ignore the overlay.

Demo-era hotfixes we can actually cite

The demo (app 4747510) launched 15 June 2026. The next day, 16 June 2026, Steam carried a short Hot Fix note. Those lines are public, dated, and specific:

• Italian language manual book blank pages fixed.
• Italian language wrong information on the Calculation Module page fixed.
• Lobby join network issues fixed.
• Voice chat delay fixed.
• Emote wheel texture stuck issue fixed.

That is the complete hotfix list we will copy. We will not expand it into extra bugs we did not see in the post. If your current full-game language pack still looks wrong, file it through Steam and check whether Lefto has posted a new note — do not assume the June demo fix automatically describes September’s build.

A later demo news item, 3 July 2026, is a platform change rather than a balance patch: macOS support for the demo. The full game launched with Windows and macOS tabs. Hardware numbers for the paid app live on system requirements. Do not mix demo RAM lines (the demo store once listed 2 GB Windows minimum) with the full-game Windows 8 GB minimum.

Before launch, Lefto also posted that the demo would come down briefly so the team could test full-game features, with a promise it would return at launch with the same slice plus extras. Whether app 4747510 is installable today is a live Steam question. Check the store. This page will not guess.

Demo to full: the delta that matters

If you only remember the Next Fest slice, the paid game is a different product in volume. The launch notes spell the marketing list; here is the same delta in checklist form so you can tick it against Steam.

Modes. Demo taught the communication loop across a short level set and a free/custom-style sandbox. Full launch ships Campaign (30 handcrafted levels), Endless (procedural waves), and Custom (difficulty, timer, modules, hazards, allowed mistakes). Details: campaign and mode rankings.

Modules. Fourteen new puzzle modules: eleven standard, three CHAOS pieces that occupy Blind Monkey. Old families — wires, direction, numpad, switches — still need the same callout loop on the callout sheet. New families belong in the modules guide as we document them from play, not from invented tables.

Space and hazards. An airplane environment ships at launch. Outages, noise, and obstructions can interrupt the relay. Environmental toys exist so monkeys can slap, emote, and waste time on purpose. None of that replaces communication.

Social and accessibility. Server browser, room codes, random role, emotes for every role, slapping, voice-synced mouths, two colorblind modes, 23 achievements (press: 16 new), full controller support. Lobby setup is the practical version of that list.

Art. Hand-painted overhaul. If a friend insists “the demo looked different,” they are correct; that is a launch change, not a random GPU bug.

Unchanged rules. Exactly three online players. Windows and macOS. Role-restricted in-game voice. No solo mode. Those belong in the co-op guide and will only move if Steam news says so.

How to verify a patch on Steam

When someone claims “they just patched voice,” do this in order:

1. Open Steam news for BOMBANANA! while logged into the client if you can. Official announcements beat the store’s aggregated sidebar.
2. Read the date, the title, and the bullet list. Copy the verbs: fixed, added, enabled. Ignore emoji-only posts that do not name a system.
3. In Steam, use Properties → Installed Files → Verify integrity if your client behaves like a pre-patch build (old lobby UI, missing random-role button, missing airplane).
4. Confirm all three players restarted after the download. A three-player session with mixed builds is how lobby join bugs return from the dead.
5. Only then update this wiki’s mental model. If you are reading a stale mirror of this page, the updates hub is the index; the Steam post is still the source.

Lefto Studio also posts on Discord, X, and YouTube. Those are good for clips and lobby LFG. They are secondary to Steam news when the question is “did the executable change.” The wiki hub keeps the official list in one place.

What this wiki will do after the next post

When a real numbered patch or hotfix appears, this page should gain a dated heading that quotes the Steam bullets, notes whether Campaign, Endless, or Custom changed, and links any guide that now disagrees with the build. We will not rewrite getting started from a rumor. We will not claim Steam Deck is Verified while the store still says Unknown. We will not recycle the June Italian-manual fix as if it were a September patch.

If you came here looking for “today’s patch notes” and the latest Steam item is still the launch post, you already have the answer: you are on the launch build. Play it. Use the callout sheet, host with lobby setup, and keep the updates hub for the next official sentence Lefto actually writes.
