Thank you for the welcome!
Yes, stacking PNGs would work, but I’m going to pay for the exporter, because I want to compensate the creators for their product–and hopefully give them a little more incentive to continue creating and improving.
Being an independent game designer, I know how much an extra few dollars can mean sometimes, so I’m happy to contribute. 🙂
I would be delighted if you’d like to check out some of my work!
