I love the art style, and the feel of the game! I really enjoyed playing it.
The only problem I had was that I got turned around a few times and got lost because the rooms and doors all look the same. Totally understandable though, in the short development time for the game jam!
I personally really enjoy breakable weapons as a mechanic because it forces the player to cycle through weapons for variety, makes looting always feel good (because even bad weapons can be used to save the durability of your really good ones), and makes an interesting 'give and take' of when you should use your best gear (against a boss or a really hard enemy, or maybe you just want to kill everything really fast).
I haven't actually played BotW yet, but I have similar experience from Dead Island. I think you did a great parody on how fast the player might cycle through weapons and how they must always be on the lookout for more. Well done!
