Jetpac - Fuel to Burn (JavaScript)

A version of Ultimate's Spectrum Jetpac in Javascript

Note that there is currently no touchscreen support (uses cursor keys + spacebar [fire] and P [pause]).
Only tested on MacBook Pro with retina display (Safari, Chrome, Firefox). Best Performance is with Safari.

1..2 Adds new graphics for rockets, aliens, items, etc. Provides Classic/ Enhanced modes for retro and less-retro-ness

1.2 Classic mode removes all of the vector effects, backgrounds except for the explosions (which are not true to the original and still need replacing with a sprite)

1.22 Fixed problem with keydown events not registering after 1S (introduced in 1.2). Reworked sprites.

1.24 Replaced font for Enhanced Version (non-Spectrum), simplified Classic title screen. Removed FPS Indictor

1.25 Improved game over, major refactoring

1.26 Added Aliens that fire lasers

1.27 Fixed CORS issue that stopped this working on modern browsers. Centered the play window.
