This was an excellent game. The gameplay window was bigger than my screen, so could only see part of the level at once and had to use scrollbars, but I feel like that's probably an issue with Itch and not your game itself.
As far as critiques go, the only one that I really have is that it would be nice if the enemies stayed still for a second or two after you unposses them. There were a few times when I shot a barrel, and then the enemy immediately walked away from it.
Music would also be nice, but then, it's a game jam. There's only so much time.
