I like the Castlevania style you went for, it feels very similar to playing the original on the NES. Transforming into a werewolf was really cool and I like that it changes up the gameplay, and I love how you got a wolf howl sound effect out of the NES-style sound limitations. Great job! Jumping through those windows felt really great too and way more exciting than just going through a door :D
I would have liked the ability to crouch, especially as so many of the projectiles look like they should be crouched under to avoid. However being able to dash through them as a werewolf was a nice touch!
