Sept 21, pitch practice

We started our pitch practices today. Our presentation is actually on thursday and we still have some things we need to finish so the gameplay demo looks more polished. I've added enemies on flight paths but one problem I came across is how to rotate the enemy ships properly so they face the direction they are flying to. There are some new code concepts(Quaternions in particular) that's hindering us, and so James and I have agreed to focus on fixing this problem first and then finish fixing the smaller things later.
