LLPLAYABLE SHOWCASE
01 / 14

01From the board to the next event

DATA2073: Battle Deck

A grid-based TCG + tactical auto-battler with three factions, progression, PvP with bot fallback and digital ownership inside one product. Build decks from over 100 unique characters in a LiveOps ecosystem with recurring quests, contextual rewards, remote content, feature toggles and an instrumented FTUE.

Enter the case

CryptoFights

A fantasy multiplayer RPG connecting tactical combat, inventories and digital ownership in a Web3 production for Android and Windows. Players build and customize fighters through on-chain equipment, compete in ranked PvP arenas and trade verifiable digital assets within a persistent blockchain-powered economy.

Enter the case

03Cards and attacks resolve the fight

Stylized Action Prototype

A JRPG prototype combining exploration, fixed cameras per area and a card system built around creating combos. Cinematic camera angles reminiscent of classic survival horror guide the player through hand-crafted environments, while the layered card combat system rewards creative deck building with devastating chain reactions and spectacular finishing moves.

Enter the case

04From low-poly to final demo

Water Battle Arena

A local arena for up to four players whose evolution from low-poly test to final demo is preserved across three public builds. Each milestone captures a distinct stage of game development, from raw collision tests and movement tuning to polished arena compositions with dynamic water physics, particle effects and AI-controlled opponents.

Enter the case

05Rhythm becomes action

Resonance: The Lost Score

A single-player 2.5D platformer where the microphone becomes a second controller: vocal pitch breaks, moves and transforms obstacles. Hum a low note to shatter glass barriers, sing high to levitate platforms, and find the precise frequency to unlock hidden passages in a world that literally responds to the sound of your voice.

Enter the case

06Networked stealth, objectives and traversal

Triple Z Stealth

A third-person multiplayer stealth-action prototype built around terminal objectives, timed rounds and vertical traversal. Teams infiltrate multi-level environments using mantling, ledge climbing and ziplines to reach guarded terminals, blending tactical stealth approaches with fast-paced combat when cover is blown during high-stakes timed operations.

Enter the case

07The spy disappears into the crowd

SLEIGHT

A local two-player noir party game: the spy blends into the crowd to steal a ruby while the detective hunts for the one movement that does not belong. Set in a shadowy 1940s mansion filled with wandering guests, the asymmetric gameplay creates tense cat-and-mouse moments where every subtle gesture can reveal or conceal a criminal identity.

Enter the case

08A catalogue with visible progress

Jigsaw Puzzles AI

A mobile jigsaw product with six puzzle sizes, image-based progress, leaderboards, social features and ad monetization. From relaxing twenty-piece sessions to complex thousand-piece challenges, the app delivers a satisfying tactile experience with haptic feedback, guided hints and a vibrant community of puzzle enthusiasts.

Enter the case

09Memory as part of the interface

AIRI AI

An AI companion experience designed to converse, receive personal stories and retrieve memories from earlier interactions. Through natural language understanding and persistent context, AIRI builds emotional rapport over time, creating a uniquely personal digital relationship that evolves with every conversation.

Enter the case

10Hidden tiles, revealed decisions

Planet Dungeon

A turn-based side-scrolling prototype built around blind exploration and decisions concentrated in a radial interface. Every step forward reveals new threats hidden in darkness while dynamic lighting and shadow casting create an atmosphere of constant tension throughout procedurally arranged dungeon corridors.

Enter the case

11One week to close the loop

RacketGO

A mobile hyper-casual game completed in one week, with fast matches, a distinct identity and connected progression. Despite its rapid development cycle, the game delivers polished touch controls, satisfying physics-based racket interactions and a rewarding metagame loop that keeps players returning for daily challenges and leaderboard climbs.

Enter the case
Lag Warfare: No Reconnection

12A map that continues at its edges

Lag Warfare: No Reconnection

Four players. One borderless map. Powers that turn lag, desync and rewind into weapons. Built during a game jam, this chaotic local arena transforms the frustrations of unstable connections into deliberate gameplay mechanics, letting players weaponize packet loss, teleportation glitches and temporal manipulation.

Enter the case

13Learning can be playable too

Bolsa Formação

Two educational experiences for IFRN: a quiz and a visual novel turning institutional learning content into interaction. Each module adapts traditional training material into an engaging, gamified format that drives knowledge retention through active participation and meaningful feedback loops.

Enter the case

14Every swipe changes the route

Radgear

A mobile skating prototype created at Demerara Games, controlled by short swipes that turn every gesture into a change of direction. The intuitive touch-based control scheme translates finger movements directly into fluid skating maneuvers, capturing the rhythm and momentum of real skating through responsive gestural input and kinetic visual feedback.

Enter the case

System

What can the team reuse?

A foundation built with Unity, C#, 3D, Card Systems to support iteration and delivery.
04

Outcome

What became better?

A playable slice with world movement, camera transitions and the foundation of a combinable card system.
