I made an arcadey shoot em' up/bullet hell with a grappling hook!

I made a arcade style shoot em' up receltyish, where you're a pirate that can grapple enemies at low health to blow them up and let you move faster. It's not too long, but I think what is there is pretty fun, and worth making into a full game, so I though I'd try and get some feedback and see what other people think of it. It's free on my Itch.io page if you want to try it out (also theres a giant crab boss at the end which is pretty cool)
