So. I like the female samurai's design and using your slash as momentum is a nice gimmick. And as per the platformer type of gameplay, its mostly slash and jump your way to the end.
Overall, I like the aesthetics, however the character design clash between the player character's 2d Design and the 3d design is awkward to look. And the slash doesn't have that sort of strong impact. It just slash and off it goes. And while I understand why, considering scope, its an assessment/nitpick I noticed. I don't know if the slow sword swing animation is intentional or just time constraints at work.
Also, it abruptly just ends. And I guess for what its worth, its fine. It just loops back to the start of the map abruptly.
