Hey FlandreScarlet64,
Well that's how I manage my projects on itchio (free + paid version). I can always rename the free zip package tho.
I get it could be frustrating but that's also a way, as a potential buyer, to see how much content you'll get with the paid version.
Moreover, I'll fix the overlay for rpgmaker this week since it censors too much content I believe 🤔.
If you need a download key, no problemo, just send me a mail at pixelart.asset < at> gmail <dot> com, I'll be happy to help 👍
