version 0.2

This is version 0.2.

I added an attempt at some mobile controls, downside is the shockwave available in level 6 and up doesn't work yet on mobile. Definitely a work in progress.

- Also added in some volume controls and a game over screen that pops up instead of just automatically restarts you at level 1.

- Added a basic particle engine effect to the enemy spaceships and a better enemy explosion upon defeat.

Next up I hope to tweak the mobile controls, add shockwave support, and then start to fine tune the enemy models and add in some more visual flare. Starting to mess around with my own custom sprites as I get acclimated to inkscape and similar programs. You can see a sample on the very first enemy.
