Thank you for your comment.
There is a step-by-step video tutorial included in the same post explaining how to configure and use the plugin, so you don't have to rely only on the code comments or plugin parameters.
Regarding the language, I'm Spanish and I primarily develop my plugins for my own project, so I write them in Spanish. Later, I choose to share or sell them to anyone who wants to use them. I understand that some users would prefer everything to be in English, but that's simply how I work.
As for the plugin being encrypted, that is completely intentional. I've invested a lot of time and effort into developing it, and I don't want my work to be copied or reused without permission. The plugin's license also clearly states that modifying the code is not allowed. This is nothing unusual—many commercial developers do exactly the same thing. For example, VisuStella's plugins are also encrypted.
Regarding the language barrier, nowadays there are plenty of free tools such as Google Translate or AI assistants that can translate anything in seconds. I use those tools myself all the time to understand English plugins and documentation because I don't speak English either. In fact, I'm writing this reply in English using a translator, just as I translated your comment in order to respond.
If you have any questions or run into any issues, that's exactly what the support post is for. Feel free to ask there, and I'll be happy to help. If a bug is found, it's my responsibility as the developer to investigate it and fix it.
Finally, if you're looking for a plugin that allows you to fully utilize RPG Maker MZ's maximum map size with parallax maps, this is currently the only plugin that does it. The other available solutions are limited to small or medium-sized maps because they are designed around the RAM and performance limitations of the device running the game.
That said, I appreciate your feedback, and I completely understand that the encryption or the language may not match everyone's preferences.
