Hey, nice game i like the idea and the feel of the hook ! Here is my feedbacks :

I feel like clicking again in the green circle isn't really relevant : I don't know when i did it properly and i loose a lot of time doing it.

It's really easy to miss your target, and then you loose instantly. Maybe add a little zone around targets to help the player. Also when i miss i would like to click again to get my hook back.

The points that you can grab are really nice, i love that they change each time. But it's frustrating when you shoot and when the point suddenly disappear. Maybe the points could flash white or black before fading.

That's cool that the enemies go to you when they enter the screen, but when you grab a point they chase you and the game become way too hard. I think it could be great if when you grab a point you dodge the current enemies.

Really nice game overall. Well done !
