Add more text to the README for people to read.  Adds the following

- Marketing and Branding
- Contact Information
- Update existing parts to reflect current state of the code-base.
- A level design guide with a lot of information about the pitfalls.

# What is this?
This will at some point be a game, written in Rust, using WebAssembly.
Ever wanted to feel like an angel? Are you sad that you can't do your annual
shift of wristband controls this year? Fear not, we have exactly what you need!
![Engel Simulator 2020](misc/header.png)
**Engel Simulator 2020** is an upcoming rogue-like title where you collect
angel-hours to finally get that t-shirt you've always wanted (_t-shirt not
actually included_)! Dive into a **realistic** and **immersive** (_2D
vector-art_) congress world and feel just like you did back when leaving the
house wasn't a crime. We've got a wide range of angel-shifts (_TODO .._) that
**feel just like the real deal**. But be careful to not loose your sanity,
because you'll be facing _dangerous_ obstacles: From _eardrum-rupturing music_
to _tinfoil-hat-wearing conspiracy theorists_, we have got it all!
Do you have what it takes to get an angel shirt?

## Project Structure
The project is mainly split into two parts: The game logic, written in Rust,
living in `src/`, and the web-frontend in `www/src/` which is mainly HTML and
SCSS + a bit of JS glue code. Additionally, some helper custom javascript
functions which are called in rust are defined in `rust-web-modules/`.
SCSS + a bit of JS glue code. Resources like sprites and levels live in
`www/resources/`. Additionally, some custom helper JavaScript (TypeScript
actually) functions which are called from Rust are defined in `rust-web-modules/`.
#### `src/` - Rust Game Logic
- `src/`: Entry-point, world setup, and game loop
- `src/`: Javascript-Gluecode, e.g. a `request_animation_frame()`
We're using the [`legion`]( ECS framework for
the in-game world and a custom state-machine for managing the overall gamestate.
- `src/`: Javascript-Gluecode, e.g. a `document.getElementById()`
- `src/`: `ncollide2d` integration
- `src/components/`: Components and closely related systems
- `src/resources/`: Game-global resources like a global clock
- `src/components/`: Components for game entities
- `src/resources/`: Game-global resources like a global clock or the canvas
rendering proxy.
- `src/systems/`: ECS systems for the game.
- `src/entities/`: Entity factories for instanciation different kinds of
- `src/`: Game state machine implementation.
- `src/states/`: Game-states like _Heaven_, _In-Game_, _Main-Menu_, etc. The
most important one is probably `src/states/` which is where all the
ECS magic happens.
#### `rust-web-modules/` - TypeScript helpers for Rust
Some things are just super ugly to do in Rust directly (anything related to the
DOM) so we have a few helper functions written in TypeScript to "offload" this
#### `www/src/` - Web Frontend
- `www/src/index.html`: Main HTML Document
- `www/src/styles.scss`: Stylesheet using Sass
- `www/src/_rc3-*`: Styles and Fonts for RC3
## Build Dependencies
Not quite sure what the dependencies really are, please add
as you find out:

## Build Dependencies

## Level Design
We're using an _Inkscape SVG_ file as the level format (yes, the inkscape
specific tags are important) and thus we use [Inkscape](
as the level editor. **There are a lot of pitfalls in designing levels so**
**please read this guide carefully!**
### Colors
We have created an Inkscape palette with the RC3 colors for your convenience.
You can find it in [`misc/rc3-palette.gpl`](misc/rc3-palette.gpl). To use it,
copy this file to `~/.config/inkscape/palettes/rc3-palette.gpl`. Then, select
it in Inkscape in the bottom right corner like this:
![select palette in Inkscape](misc/select-palette.png)
To use the colors, **click** the swatches to set _fill-color_ for the currently
selected objects or **shift-click** to set _stroke-color_.
Please use the last color of the palette (`#100e23`) as the level background.
### Layers
The level contains a number of layers which the game-engine expects to exist:
- `background`: Any graphic elements to be shown _below_ the player and game
- `collider`: A special layer that is not shown in-game which defines static map
colliders. There are a lot of restrictions in this layer, please see [Map
Colliders](#map-colliders-collider-layer) for details.
- `spawns`: Spawnpoints for game objects. This layer is also not shown and has
special semantics. See [Spawnpoints](#spawnpoints-spawns-layer).
- `foreground`: Any graphic elements to be drawn _on top of_ the player and
### Map Colliders: `collider` Layer
The `collider` layer defines static colliders for the map. Only the following
SVG elements may appear in this layer:
- `<rect />`: A rectangle collider (**Must not be rotated, this is not yet**
**supported!**). Created in Inkscape using the _Rectangle_ tool (shortcut: `R`).
- `<circle />`: A circular collider. Created in Inkscape using the _Ellipse_
tool (shortcut: `E`). **Careful**: Keep `CTRL` pressed while creating the
circle, otherwise you'll get an `<ellipse />` which is not supported.
For consistency, please color all colliders in 50% transparent red (`#ff000080`)
with no stroke.
### Spawnpoints: `spawns` Layer
The `spawns` layer defines all possible spawn points for game entities. This
layer should only contain SVG `<text />` elements. The origin point for the
text object describes the spawnpoint, the "text" describes _what_ can be
spawned. The following spawnpoints are currently known:
- `player`: Defines a possible player spawn location. One will be randomly
selected when entering the level.
- `bottledrop`: Defines a possible location for a bottle drop point. Currently,
4 will be randomly selected during level load.
Please use the `monospace` font and white text color for consistency.
