The concept for the game is great! I didn't manage to get very far as the timing required with the grapple was a bit tight. It felt a bit frustrating, when I tried to run and jump off a ledge, but just fall to my death. At first I thought the jump hitbox was to blame, but then I realized that I had sorted the abilities in wrong order. I think a unique sound effect for activating each different ability would help the player to realize what went wrong when the thing they expect didn't happen. I really like the mood of the game, simple graphics but nice looking.
