I got the sword! However, it was partly due to luck as I didn't really know what item I was supposed to give to each person some of the time. Interesting idea, though!

I was confused for a while about how to control the character, who my character was, and what I was supposed to do.
Once I got going, I enjoyed the short little trading run, helping everyone out with their weird needs - reminded me of old Zelda games where you always had to find the next person in the chain until you finally got your master sword or something :)

Uploaded a video of me playtesting!

The game was straight forward and simple. It only took a minute to finish or so, also didn't seem to use the theme of "One Time Use" at all, unless the trading was one time use? Although, I got the keyboard twice. It would be nice if there was a bit more to the game. Perhaps a sort of puzzle to solve or something. Either way the game didn't seem to have any bugs and was fun. Well done!
