JS13KGames entry for 2018, theme is "**Offline**".

## Planet Figadore has gone OFFLINE

![Planet Figadore has gone OFFLINE](big_screenshot.png?raw=true "Planet Figadore has gone OFFLINE")

Fred lives on planet Figadore in the Hercules cluster, he likes watching cat videos from planet Earth via _Parallax Shift_, but the network link has gone **OFFLINE**!

Help Fred by unlocking doors, solving puzzles and collecting cubes to pay for the entanglement repolarisation required to get his planet back online.

# Stuff I managed to add

* 2D platformer

* Full screen

* No canvas

* Works in various resolutions down to about 1366x768

* No 3rd party libraries

* All vector graphics (font bitmap rendered as vector)

* 8-bit tiny font (Repton inspired)

* Different coloured tiles per level

* Only div and span used for playfield

* CSS animations, some triggered by swapping element classes

* Simple timelines

* Retro terminal with typewriter effect

* Procedurally generated music (using frequency digraphs of Mario)

* Sound effects

* DTMF generator

* Gamepad support (for "standard" browser supported gamepads)

* Keyboard support for WASD, cursors and retro ZX;.

* Pseudo random generator inspired by BBC Micro

# Stuff I'd have done with more KBs

- [ ] More types of enemy

- [ ] Parallax scrolling backgrounds

- [ ] Better music (had to lower volume to make it more acceptable)

- [ ] Foliage or other scenery

- [ ] Support for going up stairs (this was almost working)

- [ ] Better enemy AI (more then just patrolling, perhaps jumping, line-of-sight wake up, e.t.c)

- [ ] More sound effects perhaps enhanced with envelopes

- [x] Playfield scaling

- [ ] Better game completed screen

- [x] Animate the stars to twinkle

- [ ] Enemy squash and puzzle animations

# Tools used

* [Ubuntu OS](https://www.ubuntu.com/)

* [vim](https://github.com/vim) text editor (also [gedit](https://github.com/GNOME/gedit) a bit)

* [meld](https://github.com/GNOME/meld) visual diff/merge

* [Tiled](https://github.com/bjorn/tiled) map editor

* [Inkscape](https://github.com/inkscape/inkscape) SVG editor

* [GIMP](https://github.com/GNOME/gimp) image editor

* [YUI Compressor](https://github.com/yui/yuicompressor) JS/CSS compressor

* [Google closure compiler](https://closure-compiler.appspot.com/home)

* [advzip](https://github.com/amadvance/advancecomp) (uses [7-Zip](https://sourceforge.net/projects/sevenzip/files/7-Zip/) deflate to compress further)

I had help choosing the main character name and planet name from my 3yr old son.

Also I had help designing some levels and play testing from Jessica Vines.
