Then this should have been made clear and it should have been done in a different order (making the file available first).
not rocket science.
Ok yeah it was done a bit back-to-front, but I also don't see a big deal if they're going to make it available on their website for free. If it's only on AmiStore then that's a bit of a pain for classic and MorphOS users though, but if you really want PPaint, it's not exactly hard to find through a quick Google search.
It's nice to see a classic piece of Amiga software back in development though. It would be nice to see a version for all Amiga-like OSes and the original Amiga too, rather than just focussing on OS4, especially as I tend to see a lot more people using MorphOS than OS4 on the forums these days, it would be nice to at least have a compatible 68K version for MorphOS, I'd be up for buying that.
