You can really see the roots of what would become the future of the franchise, especially when realizing the limits it was created on. But the problem lies in the fact that the game itself is a product of its time, with really annoying and uncomprehensible puzzles or zones in which it's straight up better to ignore every single enemy and just run from room to room, hoping you find the item that you need. Naturally, using the codex for calls is the best help you are going to get, but even then, it's really unclear when to make calls or where you are supposed to ask for advice. And after a few minutes the game becomes this loop of repetition in which you pray that you advance in some capacity. Still, I enjoy looking back and exploring the foundations of an amazing franchise. It's just that a lot of aspects got stuck in 1987.
