Jetpac HD

JavaScript October 2025

An HD remaster of the 1983 ZX Spectrum Jetpac with 6 levels, 5 alien types, power-ups, and neon glow graphics.

This is a modernised take on Ultimate Play the Game's 1983 classic Jetpac. The jetman collects rocket parts (Base, Middle, Top), assembles them in sequence, refuels, and blasts off — all while fighting 5 different alien types.

Each alien has distinct behaviour: floaters drift aimlessly, zigzaggers oscillate, hunters track your position, swoopers dive-bomb, and teleporters blink around unpredictably. Progressive difficulty ramps up enemy count and speed through levels themed fire, ice, toxic, and rainbow.

The power-up system adds variety: Triple Shot, Shield, Speed Boost, Magnet, and Smart Bomb. A combo scoring multiplier rewards efficient play up to 8x. The auto-drop mechanic means flying over the rocket automatically deposits whatever part you're carrying.

Neon glow graphics with particle effects for explosions and thrust give it a modern feel while keeping the classic gameplay loop. No build tools needed — just a Python HTTP server and you're playing.
