I really liked the transitions. I didn't get through all the levels because the beginning levels were rather hard, especially with the movement. I feel like the jump heights differed too much when combined with different WASD keys. The running speed felt inconsistent. But if those were fixed to where I felt like I had more control of the character, they game would be pretty good. The designs were pretty unique and the features kept my attention. The difficulty was just too hard at the beginning though. It can be the greatest platformer there is as you slowly improve your game! Keep it up. :)
