Bigger Than You Think is what you get when a master of parser fiction writes a Twine game. The result is a Twine game with an interesting, complicated map; large inventory system; and interesting narrative. It's a sort of hybrid between traditional games and modern twine games.
Does it work? It's certainly fun to get started. For me, because I didn't draw a map, it felt more or less overwhelming; you are basically searching through a binary tree repeatedly until you have exhausted all options. After a few runs, I just used a walkthrough to see the end.
The repetitiveness comes from the fact that you have to repeatedly restart the game.
The inventory system is fun. It's more merciful than I had supposed; I used up a one-shot item in one run, and was worried that I had lost my chance. However, the item was still used at the critical moment; once it is used, it is always used.
