I've got to take a few days away from Unity this week to concentrate on brushing up on some other technology, for reasons that may or may not become clear in a few weeks :) It's a useful distraction though, I've been getting over the pain barrier with shader programming today.
I have parked the space shooter type game for now as I'm a bit stumped how to make an interesting game of it, although it has been a great technical learning exercise so far. I've got a simple 2D physics based game I cranked out in a few hours that has some potential.
Either way my time is disappearing with all these public holidays, and I have fallen ill today which isn't ideal. Retiring to bed to continue my homework! I will be cranking out a few articles tomorrow from the now refactored and tidy Unity bits and pieces I've made so far.
