EatWorld

EatWorld is a hybrid-casual, .io-style mobile game where the player controls a growing black hole in a clean 3D environment. By dragging their finger, players move the hole around the level to swallow objects smaller than its current size. Each consumed object increases the hole’s size, allowing it to consume progressively larger items. Levels are set in themed environments such as parks and construction sites. Coins earned at the end of each level are used to upgrade the hole’s starting size, encouraging replay and progression.

Core Gameplay Mechanics

How it plays

M/01

Drag-Based Controls

Players move the black hole by dragging their finger across the screen. The controls are smooth and intuitive, making the game instantly accessible.

M/02

Size-Based Consumption Rule

The hole can only consume objects smaller than its current size. Larger objects remain unaffected until the hole grows. This rule clearly defines progression and strategy.

M/03

Growth & Scaling Mechanic

Each swallowed object increases the hole’s size. Visual scaling and a size indicator in the UI reflect player progress. Growth unlocks the ability to consume larger items.

M/04

Object Variety System

Levels contain multiple object types, from small props to large structures. Different environments introduce new objects to consume.

M/05

Physics-Based Swallowing

Objects are pulled into the hole with smooth physics effects. Visual and motion feedback enhances satisfaction and reinforces the feeling of increasing power.

M/06

Level-Based Progression

The game is structured into short, replayable levels. Each level features unique layouts and themes. Difficulty increases through object density and scale.

M/07

End-of-Round Rewards

At the end of each round, players receive coins based on performance. A results screen provides clear feedback and encourages replayability.

M/08

Meta Upgrade System

Coins can be spent to upgrade the hole’s starting size, allowing faster progression in future runs and improving long-term retention.

Engineering Case Study

Physics tuned to swallow cities

01

The Challenge

A growing black hole pulling dozens of physics props into itself is a classic performance trap — naive rigidbody handling melts mid-tier phones as object counts and hole size climb through parks and construction sites.

02

The Approach

Swallow detection is size-gated at the trigger level, so the hole only evaluates objects it can actually consume. Props sleep until the hole approaches, absorbed objects recycle through pools instead of being destroyed, and themed levels stream in as the previous one unloads — keeping memory flat while the chaos scales.

03

The Result

Dense, satisfying destruction with flat frame times no matter how big the hole gets, and coin-to-upgrade meta progression that makes every replay start stronger.
