Great work. Loved the different weapons, the customizations and skills, and the gameplay demonstration.
I enjoyed playing around with different weapons in the scene--the swinging attack mechanic feels really smooth, and the physics feels nice to play around. One interesting thing I found is that the weapon's size limits my mobility in tight spaces, which I think could be utilized as a good mechanic. Everything else is crafted really well, and I especially like the effects and satisfying animations in the editor menu.
Not much to say, as I really enjoyed this one. One small thing is that when the descriptions of the item I hovered pops up, it spawns directly in the middle which makes me unable to select the item. Maybe moving it up a bit could help. However, it's just a small observation.
Great job!
