No need, for I can play the file straight from JCS. Anyways, I played a bit of it. Level design wasn't all that great. You have a blue spring at the very beginning that doesn't serve much purpose except for getting the chips. You shouldn't be able to collide with the tree but you do, which gives a buggy reaction. Secrets were rather obvious, and when I entered the coin warp, I got stuck in the left wall (Let this be a lesson to never place a warp target that neighbors the ceiling or a wall to the left).

Just felt like criticizing, that's all. It's pretty good for your first though, I must say.
