While I played the browser version, though it was recommended to download, the only performance issue I saw was the bit of lag that came with rendering the 3D environment and the player's movement in it. I did however find two bugs that bothered me. The first was when opening the storage for the delivery after ordering items. The delivery storage no longer went away it stayed on the screen. Only when I was in the order book did it disappear from the screen but as soon as the book was closed it would reaper. Second, which broke the game was when I pressed X while standing in front of the selling table. the table and the item on it went into my inventory. The table had no icon, it just showed a white box and I could not place it back down after I had picked it up. I think next time you should play test your game a few times before submitting it as it can reveal bugs that went unnoticed. Though I also understand that many of these game Jams are time-limited so looking for bugs is not a top priority, however, I think you should set aside a little bit of time to do so. As I think it can make all the difference.
