VibeBlitz game jam crowns Idle Tactics as first winner

vibecode.game and Minds have named the winners of the first VibeBlitz game jam. The virtual competition drew more than 250 participants and produced 72 submitted games.

Idle Tactics: Ascension took first place. Organised by vibecode.game, a game discovery platform launched by Yield Guild Games, in partnership with Minds, an AI platform from Animoca Brands, the contest awarded the browser-based pixel-art idle auto-battler for its mix of automated combat and player-managed equipment, upgrades and boss encounters.

The first-place team received USD $1,000 in YGG tokens and USD $1,000 in Minds Cognition Credits. Tiny Realm placed second and won USD $600 in YGG tokens and USD $600 in Minds Cognition Credits, while The Last Seal came third and received USD $400 in each. Agent Fighter took fourth, earning USD $300 in each, and Pixel Abyss completed the top five with USD $200 in each.

The four-week competition unfolded in stages. During a two-week build phase, entrants used a Game Designer Mind alongside the vibecode.game platform to create playable titles. A week of public voting then narrowed the field to 15 finalists, from which judges selected the winners.

The contest was designed to address a common problem for creators using AI coding tools. While code generation has become easier, many developers still struggle with the design choices, game systems and balancing needed to turn a prototype into a playable release.

Winning entries

Each of the top five titles took a different approach to small-scale game development. Idle Tactics: Ascension focused on progression and timing rather than direct combat control, shifting the player's role to managing a character's development.

Tiny Realm, the runner-up, used a real-time strategy format in which players gather resources and build defences against waves of insect attackers. The Last Seal, which finished third, was a 2D side-scrolling action platformer built around precise movement, combo combat and a special move with a cooldown mechanic.

Agent Fighter, in fourth place, was a browser-based 2D fighting game built on a deterministic engine that allowed human players and AI agents to compete through a shared queue, economy and leaderboard. Pixel Abyss, which placed fifth, was a pixel-art roguelike dungeon crawler with unlockable abilities, hidden rooms and collectible loot.

The judging panel consisted of Gabby Dizon, Co-Founder of Yield Guild Games, and Mohamed AbdelKhalek, Game Designer at Animoca Brands. They assessed the shortlisted entries on plot coherence, playability and fun, creativity and originality, and technical execution.

Another constraint shaped how entrants built their projects. Each submission had to fit within a 32x32 plot of land and form part of a wider neighbourhood, with teams able to earn bonus points by making meaningful references to a neighbouring build.

AI and design

The contest also tested how AI tools might be used in game creation beyond code writing. The Game Designer Mind was presented as a way to help participants work through design hurdles and move from an initial prompt to a published title, with feedback from a community audience.

That combination matters for Yield Guild Games as it expands into AI-related projects and uses community testing and voting to identify promising new titles. For Animoca Brands, the format also aligns with its interest in persistent AI agents and shared virtual environments.

Yat Siu, Co-Founder and Executive Chairman of Animoca Brands, said the results showed how AI support tools could lower barriers for creators. "This game jam is a clear demonstration of what happens when you put the right creative tools in front of a community that already knows what to build," he said.

"Over four weeks, we watched ideas move from a single prompt to games players genuinely wanted to keep playing. It's an early look at what persistent AI agents can do for creators once the friction of getting started is removed."

Dizon said the project also fits a broader push by YGG into AI. "YGG is moving heavily into AI, and vibecode.game is one way we bring our community into that world with us. It acts as our discovery layer, turning community playtesting and upvoting into validation for new titles," he said.

"Seeing builders work with the Game Designer Mind to ship great games within tight constraints shows how well this model works. It gives us a clear path to find, test and support the next generation of AI creators."
