I stumbled upon the development of Terranigma 2 a few years ago and presumed the project was death. Got a hunch today to check again, and what a pleasant surprise! Just watched some footage on YouTube, looks pretty awesome! I wonder in what middleware you are building this engine? Unity, Godot or something else? Will there be an English translated version along the way? And do you plan to release the engine itself for other creators to create their own Terranigma adventures?
Keep up the amazing work, I'll be following along!
