Thank you for the feedback!

I struggled a lot with the movement. I will try to improve the movement of the player by making him slow down completely after a second.

I know that the damage is low, especially for areas with tons of enemies. I should have made the combat harder, not longer.

The grappling hook was indeed underused, but I did not have time to make more use of it. If I update the game with a new level, that level with contain more use of the grappling hook.

The "bug" in the first level is not a bug, but rather something that I did not notice until the jam was over. If you look closely, you can see that the sprite is also different from the sprite in the second level.
