Hey,
I assume this message is like throwing a bottle in the sea, as you are inactive since a year now.
I m a game dev student in Paris, and last year i've worked on a sokoban game, developping an isometric grid system and other mechanics on Godot.
I've also grew up playing Dofus, a tactical MMORPG in 2D isometric.
This kind of game is something i m loving since childhood.
Your game is the perfect fit between this kind of games and my favorite universe, tactical fits so well with One Piece and you did a great job.
I would love to see the source code. I know you already answered it's a bit of a spaghetti code but i would write my own code, yours being a nice help to quickly find out how to deal with some things.
I would be so happy to work on a project of this kind on my free time, just for my own satisfaction, it motivates me.
So please if you read this, contact me, i know you don't have much free time but i would not bother you, i just wish you could share me the project.
