Super cool use of the ASCII design to create a puzzle game that is easily understood and not super frustrating to have to try again when you fail.
You have a fair few typos / wrong uses of things like your vs. you're / to vs. too in your dialogue, as well as some missing apostrophes and commas throughout. Nothing that causes your narrative to be confusing or lose meaning, but definitely something to look into if you're wanting to polish this up a little more.
Overall a very fun experience.
