The shadow mechanic felt really fun and unique, it's simple but I feel ike you can really refine it if you're given enough time. One thing that felt a little frustrating was the hit boxes though. I noticed that sometimes I would get hit when it felt like I maybe shouldn't have, or that my sword attack didn't have a very large range so it was hard to hit the enemy without also getting hit. This was only one time, but I did have a situation where an enemy hit me right after they died. It was probably a weird timing thing from the visuals. Your game was fun, I'm just giving you this feedback so you can improve on your next game. Great job, especially for your first game jam
