I believe Zeliard (and also the sequel to Thexder) were Game Arts games, as well. Thexder was one of the first computer games I ever purchased. (Sierra’s 3-D Helicopter Simulator was also one of my other first games… I bought both around the same time.). Although I preferred the adventure game titles, Thexder was a very fun game with great graphics and music. Maybe some day I’ll get it running again and try to finish it. It was a bit challenging, and I don’t recall it having the ability to save your progress.
