The Summoning

The game starts out strong with an interesting story and magic system, but then it starts to drag. The levels become needlessly complicated and there's just too many of them, that add nothing to the story and are just there to prolong the game. You'll never know what items you're going to need for puzzles (so save often and in different slots) and eventually fun turns into work. The game reaches it's peak, when you reach the knights. It should have been over then, but you're still in the first half at that point.
