I'm experimenting further with some advanced PNG compression techniques for the next build.
I need some large projects to play with though - ideally with over 100 images - and in both retro (pixelly graphics) and modern style. If all goes to plan, I should be able to get significant size savings on retro games! Possibly up to a 50% file size saving, which would be amazing.
If you have a project that would be suitable, I would much appreciate if you could send it to firstname.lastname@example.org. Obviously I will keep them private and not share them with anyone!
