This game is, I believe, written in a custom parser that the author has used in other games. It works well here, with elegant javascript integration.
You play as an adventurer/junior magician gathering spell ingredients for you boss. The spell ingredients are all food items.
The map is laid out visually, making navigation simple. Areas vary in complexity from mostly-empty to containing multi-level structures with puzzles in each level.
The primary puzzle-solving technique is inspired by The Wand by Arthur DiBianca. You say a magic spell in your grimoire, and point your wand at something for that spell to take effect. The spell language follows patterns that you have to discover.
I haven't completely finished the game, finding only a little more than half of the ingredients on my own and 4 more with hints, but the game lets you stop at any point, and I've gotten up to an E for Exceeds Expectations.
The puzzles are rich and interesting and systematic, and vary from trivial to complex. I didn't connect on an emotional level, more just skimming the surface, but that's more due to personal taste. Overall, well-done and enjoyable.
