Labeled as "Non-IF", one might wonder... how do you make something in the z-machine that isn't... Interactive Fiction? When a text engine--designed for text games--is bent and twisted into something else, one can be split between thinking "Why? Why would you do this?" and being incredibly impressed that it was done.
Other titles have turned what are normally graphically based games and used text to "draw" out a game.
"A Tight Spot" is basically (Spoiler - click to show)Sokoban implemented using text as graphics
Many other titles have done this, and this one does it well. I should add I played this on Parchment (an online javascript player for z-machine games)and it worked just as well. It's impressive that it works at all, but how about the game?
I found myself as addicted to this as when I've played it on any other platform. I can't bring myself to give this 5 stars compared to other "text" adventures though. Not using traditional text makes it both amazing but also makes it "not-IF". Try it out and have some fun.
