Nice and polished game! Everything worked really well together. I encountered a bug where you couldn't reach carrots and tomatoes that were positioned near walls. Also would've loved to see more content like what to do with the coins acquired and possibly traps to capture the player? Avoiding the knights was quite easy even if you get noticed you can just run and hide with no problem. Just spit balling ideas here, but another interesting mechanic would've been carrying the items and then selling them before getting coins but I guess that kinda changes a lot of the game.
Good job!
