Hole Rush

Create an arcade game that is understood in a second and played with a thumb: a hole that grows by swallowing everything smaller than it. The difficulty lies elsewhere: making the escalation climb, from the cup to cars and then to buildings, keeping a fair difficulty curve across dozens of levels, and staying smooth even when the street is full.

A readable escalation

The hole moves on its own; the player steers it by sliding a finger. 30 object types, visually sorted by size, indicate at a glance what can be swallowed. Hitting something bigger than you slows you down without ever making you lose. Each level ends with the Big Feast, where the hole devours entire buildings.

Progression that makes you want to come back

A setting changes every five levels (downtown by day, beach, city at night, supermarket), with coins, stars, skins, bonuses you can feel in play, and a daily challenge.

Difficulty tested by bots

The tests have bots play real matches: a diligent player must win, a clumsy player must lose at the right levels. A setting that creates a difficulty spike fails the build.

Measured performance

All graphics and all sounds are generated in code: no bundled images or sound files. Frame-by-frame measurements showed that the game logic takes 0.35 ms per frame; the stutters came from the sound, moved to a native audio engine, off the main thread.
