Art is nice, characters look cute.
Animation looks good but the way the motion themselves look rather odd. When attacking, it might be better to have the character look like they are leaning forward a bit more. Standing perfectly straight almost leaning backwards and swinging that knife doesn't look as nice as leaning forward and swinging.
Gameplay needs a bit more polish, in a way that makes everything string together better, maybe some particle effects here and there, enemies can have some knockback effect like the one one the player, I am sure these will benefit the game visually.
Overall pretty good.
