I had planned on keeping this thread updated daily but I've been working on music and sound effect stuff mostly and screenshots of music and sound effects aren't very exciting...
I will try to record some videos of gameplay once I get the final music in.
The one thing I have added other than sound is a new bombing ability to the Invaders (saucer guys). They drop little egg bomb things (seen in this screenshot above) as they fly towards the pod now. I've been told they are the most terrifying thing in the game right now. So that's fun.
I've also tweaked the way the turret works. You can now redeploy it anywhere, but while it's out, your shields no longer regenerate. So you can switch the turret around more depending on where you're being attacked most if you want but you're weaker while it's out.
I also got trophy/achievements working really well right now. I'm working on the trophy screen at the moment.
I've had some more feedback from testers and have some new ideas for tweaking the difficulty as well (everyone still complaining that it's too hard at first). Invaders won't show up for 30 seconds in a round, and the big green guys won't show up for a full minute (possibly two... still testing it) now.
With all the sound effects added, the game is really coming to life right now. Looking forward to sharing it with people soon!
