Codex Capris is a really decent game. Although the fact there are only 2 elements - dark and fire - sounds really unusual, it's a decent game. There are pretty simple graphics, but I don't mind that at all - they look unique and I personally could enjoy the game with ease.
You also have ranged weapons and I remember having a small issue with aiming with them. It's a shame the game doesn't autosave, but maybe the game is just really short. I still think this game deserves to be a full-sized game; with more content.
