Development continued a bit this week on Fasteroids. After a bit of a false start I've now implemented an extra life every so often, I'm not saying when so I don't spoil it. I also tided up spawning code as implemented in the Shaun Spalding videos, using a for loop rather than just creating several instances. This made it easier to implement more difficult levels. If you look at the screenshot you'll notice I made it all the way to wave 20 (of course this is with the extra levels implemented).
I'd planned on implementing a bit more this long weekend but life got in the way.
