About Wallflipper
A fast 3D arcade runner in the browser. You tear down a neon corridor at full speed, steering with A and D or the arrow keys to climb the walls and pressing Space to flip to the opposite surface, so the floor, the walls and the ceiling are all track. The aim is to follow routes of fragments, dodge traps on the surfaces and stay alive as long as you can; the HUD counts distance and fragments, R reverses your direction, and a crash ends the run with your distance. The entrant gives “the flipping gravity idea” as the inspiration. The game is one of the small standalone pages in Evgeniy (Eugene) Trifonov's “vibe tools” collection, where it is listed under mini-games. It was made for the Cursor Vibe Jam 2026, whose rules required at least 90% of each game's code to be written by AI; the official submission lists Pi as the tool, and it finished 611th of 945 entries. Free in the browser, played with a keyboard, with music and sound that can be switched off.
How it was built
Partially verifiedIn the official Vibe Jam 2026 submission the entrant lists “Pi” as the tool and answers Yes to the AI-written field. Pi is not one of the AI tools tracked on this site, and the entry does not say more about it; no devlog describes how it was used or which model ran it.
- OfficialJam rule 3: at least 90% of the code has to be written by AI. — Vibe Jam (Pieter Levels)
Built for the Cursor Vibe Jam 2026 on Three.js with Pi named as the tool. The whole game is a single HTML page with its own script, loading a local copy of Three.js and the jam widget, and includes a Vibe Jam portal.

Verification notes: Tool (Pi), engine (ThreeJS), genre (Racing), pitch, inspiration and the multiplayer (No), mobile (No) and portal (Yes) flags from the entrant's answers in the official Vibe Jam 2026 games data (submitted 26 Apr 2026, 19:04 UTC; final rank 611 of 945 entries, no award), re-read on 6 Nov 2026; rule 3 on the jam page requires at least 90% AI-written code. Pi is not one of the tools tracked here, so the tool is recorded as undisclosed with Pi named; the entry does not identify the product further. Controls, HUD and the start text from the game page on 6 Nov 2026; the game was not played. Developer: the X profile @phillennium gives the name Evgeniy Trifonov and links the Telegram channel t.me/expectfun, whose page names Eugene Trifonov; expectfun.github.io's home page is titled Eugene Trifonov and links the vibe tools page that lists the game, so the two spellings are treated as one person. No location or team size is given. The same vibe tools page also links separate LLM utilities (for example a token counter that uses the Anthropic API); those are other pages, and the game's own code makes no calls to AI services. The jam page's widget counters showed 70 plays and 59 portal transfers for the host expectfun.github.io on 6 Nov 2026 (observed; the counter is per host, and plays are sessions, not players or downloads, so neither is recorded as a metric). The release date is not stated; the jam submission is dated 26 Apr 2026.
