# 怪獣ドカン！ KAIJU DOKAN!

A 3D browser game in which you control the giant kaiju Dokagon and destroy a waterfront city at dusk within the time limit to increase your score.

## Description

A 3D action game built with Three.js + TypeScript. The player controls the giant kaiju Dokagon and aims to achieve a city destruction rate of 40% within 4 minutes.

Buildings are made up of floor-unit blocks; only the attacked parts collapse, and destroying the foundation causes the building to topple and involve neighboring buildings as well.

Continuing to destroy raises the combo multiplier up to a maximum of ×5, and by storing energy you can unleash a magma breath.

As time passes, tanks and attack helicopters appear, and you intercept them with stomps, punches, tail attacks, breath, and roars.

When HP reaches 0, the game is over.

It supports keyboard + mouse, keyboard only, gamepad, and touch controls on smartphones and tablets, and you can configure graphics quality, screen shake, volume, and other settings.

No image or audio files are used; graphics, sound effects, and BGM are all generated in code.

The author explicitly states that Claude Code was used in development.
