I really enjoyed playing this game, thank you for making it! Didn't get a chance to play the multiplayer, but the singleplayer was amazing. I saw you might need help with a Godot 4 port. My dream has always been to create a ninja platformer, so if you still need someone to help, I use Godot 4. I do have to admit I'm still a beginner with only one project released so far and another on the way that I'm working on collision and level design for, and I'm not at the level where I feel comfortable with 1 on 1 collaboration, but if you end up putting the code on Github, I would love to try porting it to Godot 4. If you wouldn't mind, I might also try expanding the singleplayer with more of a story and maybe more of a metroidvania feel. I would also give you credit for the project. Anyway, let me know if you would like me to help you, and I would be honored to continue this project. It looks like it has a lot of potential.
