Rygar on NES was one of those games that felt like entire another world. It felt really big at that time. Great mysterious atmosphere and exploration feeling. Ed Findlay trying to create some kind of Rygar remake or sequel. He called it Rygar Vengeance and it can be found on his site https://www.retrogamer3.com/ . In case site not works he also has his youtube channel.
At the time I write this the game is beta version 1.4. Below I post some screenshots. And the only short gameplay I found is in the Ed’s youtube teaser video 3 years ago. I’ll post it below screenshots.
