Just saw my shooter in progress mentioned on IndyGamer - how cool is that. Well, here's the development news as it goes.

The game is no longer going under the name, Bjorke, it's now called Interferon: Core Defence - based on the theme of protecting CPUs from incoming viruses (antivirus, interferon etc).

Ive had a couple of hours tonight so I've added the powerup framework and some added extras, along with the associated graphics. The game is starting to play more like a frantic shooter which is zapping up time "play testing". Other updates, I'm going to try and release this one shareware (along with 2 others in the next year or so). The core SVG renderer has been updating for performance, as has the collision dections. The waves are now defined in XML so they can be built up and tweaked quickly.

Finally, some up to date screenshots:

looks really nice! A

looks really nice! A question though: how do you do the glow of the units? Is it just a texture with an alpha channel?

Kev: Nope, no textures at all, just vertex colours.

Kev, could you please do me

Kev, could you please do me big favor and add a little code/image example how you did the glow?
I think I'll never get it :-(
Or do you have a link where it is explained with sample images and code?

Kev: I just did what seemed logical, for each line in the svg I create a quad with the line across the centre. I set the outer colour to black and the inner to the colour the line wants to be. Overdraw this with a additive blending and a few different shades to build up a glow. Wouldn't really work on sprites of course, I'll try and put a demo into slick for it later.
