I've recently put up a notice for how you can tip me for my work on REXPaint, as thanks (because no, it doesn't mean I will be releasing new versions any time soon, though yes that will continue to happen occasionally as I have time
).
You can read how to do that on the right side of the
downloads page.
As usual, REXPaint has always been and always will be free! Sharing the cool things you do with it is as good as any tip
. On that note, while we already have the gallery, I plan to also add a new "projects" page that showcases games and software that make use of REXPaint.
