I agree with Ross, PNG cannot compress significant better than ZIP, they both use about the same algorithm. Unless you convert your PNG to 8 Bit.
There is one thing you could do: convert them to JPGs! The good part is: you don't need to alter the sourcecode, simply replace the BMPs by JPGs that are named BMPs. Blitz will noless load em. You may have to visually check every texture and decide how much loss is bearable. Some textures can be comressed down to 40% quality, some require at least 80%. After all you'll still save about half of the (texture)space compared to PNG.
You could also offer two versions of the Demo for download, where you'd explicitely state the small download is using reduced Graphics Details. So people would know about it.
Didn't play it yet, but I think generally this is the best Car racing game written in Blitz so far! Nice Idea to add RPG stuff to it!
Good luck with this!
