As someone said, it does crash when you jump and try to talk to the guard. I was trying to come back to the second guard (what word do I need for him?) and jumped while trying to get past guard number one.
It's a very fun mechanic, and I enjoyed it! However, the hit box for grabbing the words is a bit funky and left me clicking at it, hoping to grab the word. Maybe that's on me for playing on a small resolution.
