It's in a bit of a rough state, but it's of course a prototype as you said in the description.
kinda see the vision here, feels like the sword idea has potential, I think it needs to be more obvious when you hit the enemies.
You know what would be cool, some cool abilities that are different for all swords, maybe some rarer swords has abilities and some more common doesn't. I see you've got an inventory in mind, so that's cool.
I like the concept, intrigued to see where you're taking it!
All things considered, actually a bit enjoyable for what it is currently :)
Good luck!
