Oh, I did get the ending! I got the good ending of reuniting the strange man and his one-eyed bear friend. And I got the bad ending of being kicked out of the carnival for shooting bears instead of ducks.
I think everything works quite well for a text based adventure, so I don't have a lot of useful feedback to give. For something like this, all I can recommend is 'more content' which is asking a lot in a ten day game jam. :) I suppose if you implemented point-and-click for the options rather than relying on keyboard controls it would improve accessibility.
If you add something to do at the third stall I'd be happy to try it out!
