About Hollowlands
A multiplayer survival action game in the browser, which the developer calls an MMO. You explore an endless, procedurally generated world with other players, gathering sticks, stones and vines, crafting a stone axe, bandages and torches, building a crafting table, a campfire for cooking raw meat and a bed that sets your respawn point, and putting up walls, floors and ramps; you can also climb trees and walls. A list of goals guides your first steps. The entrant names The Legend of Zelda: Breath of the Wild as the inspiration, and the page's own description mentions aesthetics inspired by it. 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 Claude Code as the tool. The developer, André Elias, later published a Portuguese-language video about building the game for the jam with AI in 30 days. It finished 94th of 945 entries. Free, on desktop and mobile browsers; it needs the developer's game server to be online.
How it was built
Partially verifiedIn the official Vibe Jam 2026 submission the entrant lists Claude Code as the tool and answers Yes to the AI-written field. The developer's own YouTube video about the game is titled “Fiz um jogo online com IA em 30 dias valendo $25k” (Portuguese: “I made an online game with AI in 30 days, worth $25k”); its title and description do not name a tool. Which model ran Claude Code is not stated, and the submission covers the jam version only.

Built for the Cursor Vibe Jam 2026 on Three.js (with React Three Fiber), with Claude Code named as the tool. Online play runs on a Colyseus server hosted on Colyseus Cloud. The developer's video description says the 30 days of work were followed by extra time for editing the video.

“A MMO survival game with infinite world to explore and build”Verification notes: Tool (Claude Code), engine, genre, pitch, inspiration and the multiplayer, mobile and portal flags from the entrant's answers in the official Vibe Jam 2026 games data (submitted 30 Apr 2026, 18:44 UTC; final rank 94 of 945 entries, no award); rule 3 on the jam page requires at least 90% AI-written code. Developer: the jam data gives the X handle andreeliasdev, whose profile (display name “André → andreelias.dev”; bio “I do Web Games, SaaS and YouTube” with a Brazilian flag) links the game; the YouTube channel “André Elias | Dev” published the video about it. We did not watch the video. Its Portuguese title and channel come from YouTube's oEmbed data; its 12 Oct 2026 date and description (30 days of work, the jam's prizes, a “play the game” link to this address) come from a copy of the video page saved on 4 Nov 2026, because the page itself showed us a bot check. The developer's location and team size are not stated. Crafting items, goals and building pieces come from the game's scripts. The game's code talks only to its own Colyseus server, PostHog analytics and Sentry error reporting and the jam widget; no calls to AI services were found (the PostHog “conversations” code is a support-chat feature, not used for gameplay). The jam page's widget counters showed 4,066 plays and 1,942 portal transfers for hollowlands.andreelias.dev on 4 Nov 2026 (observed; sessions, not players or downloads, so not recorded as metrics). The release date is not stated; the jam submission is dated 30 Apr 2026.
