Thanks guys, I guess I'll have to research the various options a bit. Make sure I'm getting something that I'll like. My McAfee subscription is paid up until August, so at least I have some time to look around.
Well, I finally got another beta release of Butterfly Fury posted on Wooglie.

Some of the things I added/changed:
1. The waves are now in multiples of 10 instead of 25, and the droids are a bit weaker. So the player should move through the levels a bit quicker and easier.
2. The droids now explode with a pretty lens flare. That adds a bit of gratification I think.
3. I added a subtle glow to the magnetic pulse, and it has a sound now.
4. Collectibles have a sound when you pick them up.
5. There is a new "tips" menu page that explains how to pick up collectibles, amongst some other hints.
6. I flattened the ground a bit so the droids aren't so close in some areas.
I also spent a couple of days hunting down a bug. I thought I had squashed it, but it showed up again today. Grrrrr. I think the collision event is triggering more than once per frame every now and then causing an extra droid to pop up inside another one every so often. I think the web build is limited to 30fps though and I don't think this bug shows up in the actual game, only when I play it back inside Unity. I'll have to look into it a bit more though and make sure.
Anyway, let me know what you think.
