I like the craft motif; the buttons being your health meter was a cute idea and I like that the sword is a single half of a pair of scissors. They only complaint I have is that the boss hitbox would be a little inconsistent sometimes and it feels like I was getting hit by it when I was outside of it's range but it wasn't unmanageable or anything.
I was serious about getting the secret ending so I spent countless times getting tagged and then ramming myself into the boss to restart without having to re-open the door and I think I actually teared up when the secret ending played.
