This was a great time! The boomerang aiming takes some getting used to, but once you get the hang of it, it feels really nice (and props for having a tutorial at the start to practice it without danger). Music is intense and cool, and the sound effects are nice. Love the visual style, too.
I also really liked the flow of the game. I felt like the most intense part of each room was the very beginning and you have to react fast because everything rushes at you, and then if you handle that part right, you can get into a nice flow with it. Not sure if that was intentional, but I loved that little adrenaline spike at the start of each room.
All-in-all, this was a fantastic jam entry. Great work!
Also, I love that it was written in LÖVE! :)
