I'm liking this game a lot, I think the camera feels a little weird, you can use two vertical speed for three cases, if the character gets near of the vertical edge or lands in the floor you can use a the maximum speed but if it's mid'air and not on any edge the camera could be following the character in a slower ratio.
Also I think moving the camera up and down pressing W and S keys could add a lot of control to the player. Can't wait to play the whole game!
