If you are considering another engine, then I would recommend Godot since it is a lot easier to use, even compared to unity. if you want to try out a completely new engine, then I would recommend ct.js.
Thanks for the recommendations, but I already have my own engine I’m gonna use for the port. I much prefer raw code over visual editors (for layout) like Godot’s, since it gives me much more control over the performance and overall structure of the game.
