Loosen up a little

After A long while alpha 15 (should be 20) has released and with it a few overhauls and QOL changes.

First things first major additions

1) A tutorial, now you can actually learn to play the game instead of fumbling about with the controls. The tutorial currently serves to introduce the player on the bare bones essentials and is subject for a (much needed) overhaul in the future.

2) sprites, spawns and squads were completely overhauled. Spawners used to spawn the "squads" all prebaked into one object that would change its sprite based on how much HP it had left. Now the spawner will continuously spawn every member of the squad individually until the whole squad spawns.

What does this mean exactly? 

1) fewer lines of code to swap between sprites

2) More options to balance the game with

and lastly

3) the game now looks slightly less janky than it already is.
