It is definitely not perfect, but you can see the dedication, keep it up. And i just love the janky paint aesthetic)

I had problems with the grappling, as well. It really only seemed to work when it wanted to, and when it did, it flung me into random directions with an absurd amount of force that render me unable to control the character (even left and right had no real effect at that point).

That being said, I really like the sound design of your game! The SFX and the music both really fit the game's aesthetic and adds to its experience. Overall, I feel like I got an idea of what your game was supposed to be and that it has a lot of potential. I think you just needed some more time to really get the controls set just right.

The game is really glitchy and hard to control. Sometimes when I jump I barely go a few pixels, yet if you spam the jump key at the bottom you can build up speed and launch yourself without using any extra fuel which I don't think it intentional. Missing with the grappling hook is frustrating because it doesn't return so there's nothing you can do to recover. The art and aesthetics are decent though.

For your first game this is a amazing effort! I loved where this was going and the grapple hook was a nice mechainc to try and get the hand of. I would say it needs a little tewaking so that the player is able grapple under platforms and boost up from that, as the position where the grapple actually worked for me was hard to get in a pinch. Still a great game! and impressed with the artwork considering what it was made in, well done!
