I enjoyed playing. Loved the music and thought it fit really well. Jumping and grappling around was fun too. Wondering if a controller option might be nice (I'm not great at WASD platformers). Also seemed like sometimes my grapple would disconnect too soon or not connect at all when it appeared to hit the ceiling. Definitely a challenging game (I was finding myself wishing I had more health or could pick up health pickups).
Great job
