I really love the movement it feels great, this game is just awesome and the fact that it is your first jam is just so impressive, i felt sad ending the game so soon but that s okay i can imagine you didn t manage the time well since your new to this but overall very solid entry. Great work!
btw the wall hanging thing is not a bug it s friction you can disable it by creating a new physicmaterial2D and setting the friction to 0 then assigning it to the rigidbody2D there is a spot for it there.
