I like these type of games but it has some issues not allowing it to be smooth and therefor fun..
Make the camera focus more on the mouse instead of strictly on the player object, look into camera lerp. It makes it way too finicky to aim with the camera moves away from the mouse. Also the grapple should fly out faster + perhaps have the clickable zones much bigger (initially i thought the whole light area was clickable). These three things put together creates more frustration than fun. Which is a shame because swining games are fun.
If you make it more smoother you can still play around with difficulty by making different sizes of hook zones and hooks that break etc.
Good luck, looking forward to see how this develops.
