This is my first Quest game; as such, it includes a map that you fill out as you explore, and lists all important objects in a room as well as your inventory at all times.
Besides the usual inventory, the game has a great additional mechanic that gives you an additional way to solve puzzles. This was fantastic, and I wanted to keep playing just to explore the mechanic.
The story was fun, but not especially motivating. The parser was terrible; so many obvious synonyms were not implemented that the game became a frustrating guess-the-verb game too frequently. However, the new mechanic was so fun that I kept playing anyway.
