This game was really fun! I really liked the concept of the game, which did a good job of combining both puzzle and action gameplay effectively, which you don't see a lot. It got really tense in the last level! I also thought that the story and concept was funny, and really enjoyed the art style.
I was a bit confused with where to click when I was holding items at first. With the items being so big, it wasn't obvious to me that I was still supposed to click where my mouse cursor actually was, but it made sense once I figured it out. I'm not really sure how you could make that more clear though. I also noticed that there were some issues with some of the UI being the incorrect size and position when in full screen, at least on the web version (in particular, the mission complete screen). Other than those things, I thought that this game felt really polished, especially for a game jam game.
I think you have a great game here. I'd honestly love to see this become something more!
