Quick and dirty how-to-play

A to-do for this game to be considered "done" as a MVP is to attach a Tutorial to it describing the core mechs. 
This will do for now

How to play

Click and drag blocks with the mouse to move tiles and arrange your ship. Block asteroids with the core block (the yellow one with a face) to generate new tiles from the asteroids.

Tiles can be combined to create new tiles.
Press shift and click and drag the mouse between adjacent tiles. This will allow you to select a set of tiles which can be transformed into new tiles if the pattern is a known recipe.

The only known recipe is a metal tile.
Select four red standard tiles in a clock-wise order to generate a metal tile.
