Agreed. While it does cost money, they are entitled to the money they get for the work they put into it. I wish it was Open Source because I stand for libre software, but I get why it isn't. Its really hard to make money with open source...KDE and GNOME, the two most prolific open source development companies(even moreso than the Linux Foundation) barely get any money from their endeavors at all. To call them prolific is an understatement...sometimes I check the licenses of proprietary software for Windows and most of the time I find KDE or GNOME-based software somewhere in it.

I got PICO-8 in a bundle from 2020 and only recently realized I had it, but I was planning on buying it before I saw it in my library anyway. I might throw them money to help them out despite getting it in the bundle because man...Im loving this thing.
