I think this has the potential to be fun web game, but it needs a bit of polish. The mouse detection feels off. I suspect you have to click just above the hook rather than where it feels like it should. You should make it so if the hook is touching something when the player clicks it picks up. Also, there needs to be a proper game over screen when you die. Depending on where you die you can just idle and pick up extra coins if you're patient enough. Also, 1 health makes the game feel frustrating. The player should at least be allowed to make a few mistakes
I hope this helps!
