The game is really fun and addictive, but it could be improved.

The hook mechanic is fun, but I really don't like the it spins and then you click mechanic, you should have made go towards your cursor.

Also the hook could be made more juicy, like if you chance it to go towards your cursor it will probably get easier, so give it gravity, and some cool sounds and camera shake on landing and the game will feel a lot better. Also if you give it physics, when the player starts going towards the hook, the player should fall as well, and then get pulled back, so you could do really cool swings very you hook to a surface, and let go of the hook, and conserve the momentum. That would make the game a lot more fun, by removing the annoying timing thingy, but still keeping the difficulty.

Then the background, it's just bland color, you should make it like a cave or something and give it parallax, and it's gonna look so much better than just a single color.

And the coins, there's no use for them, maybe you could buy some skins or something like that with them, so you would be actually incentivised to take them.

Also you should add some death particles, because the player just disappearing is really unsatisfying.
