It felt slow and the movement was frustrating. Visual design for areas and the character could maybe be improved. I wouldn't have felt as frustrated with not being able to jump if I didn't have legs.
I'm sorry you feel that way, I really wanted to make smoother movement and more vivid areas, but I was doing the jam solo and I'm not a very good programmer and especially a very bad artist, but thanks for the feedback anyway, when I polish it up this comment will come in handy :)
