I'm glad your efforts payed off :-)
Game development is a hobby for me (for now). So I'm not pulling hard for attention but more feedback to improve my skill are always welcome.

Good on you for making an engine that adapts to external files without the need to change your code. Most of the times, my prototypes require me to edit the game engine code and recompile.
Yes, it makes sense to develop a prototype. So you can have something to play and test your ideas early on.
BUT, you don't have to scrap your prototype. You can replace its simple graphics with polished art and add your sound tracks to turn your prototype into a final game. Ideally, you want to build a modular prototype where you can add or remove elements you want or don't want in the final game.
Can you edit existing sprites?
In Rome Protector, when the player swings the sword, the feet don't animate even when moving because the sprite sheet lacks sprites that combine sword swing and feet movement. The sprite sheet is Player.png from the Common directory.
In Return From the Tavern (the only game of mine I had translated), the text files don't use CSV but use custom tags to refer to in-game variables, icons, character names, key identifications and scene transitions. How do you adapt to the need of custom tags?
Having more payment options would be beneficial to both the game developers and to Itch.
The game developers can choose the payment processor that offers the best convenience / fee ratio and is available in their country.
Itch becomes more robust to external constrains imposed by just a few payment processors.
Would you like to play my game Return From the Tavern and share your feedback on the difficulty.
Adding new languages proved to be more work than expected. Almost all languages added required new characters that were not in the pixel font and adapt the game code to use the new characters and add the ReadMe in the new language and update all the ReadMe with credits to the new translator... both for Windows and Linux.
The web upload is ideal for small files like 10MB. It worked before so it feels like a software regression.
