Part of me really wants to give you a fair shot. so if you can find what is causing the crash, fix it, and leave me a link to that project, I will rate based on that. but the game keeps crashing so I can't really give an honest review based on what I've seen so far.
maybe try it just as a windows download?
Here's the link to the download version: https://domochico.itch.io/duck-mob-download
I did play a version that didn't crash. I take it you're still pretty new to unity. The tutorial build up was good, difficulty curve was well managed, and you fit the theme extremely well. So if this is your first game jam, the fact that you got that much done well is a very good sign, keep practicing.
Now for the bad news. the looks and level design aren't great. I take it you either have never done 3D modeling before, or have done very little of it. I would recommend downloading blender and looking up Blender Guru on YouTube, he's a great intro to blender which is great for unity models. although animations is more of a brakeys thing. Also, you always want players to have a way to quit your game. If you are in a pinch, just have an if statement with application.quit(). A basic menu scene is usually a good idea too.
So while I can't score you very high, for what I'm guessing is a pretty early usage of unity, it's definitely not bad. you got all the hard stuff right, it's just your technical skills couldn't quite execute it. nice job, keep going.
