Nice game. Got a little challenging with the pink player but enjoyable! The player sounds are great. I like the parallax background as well and the art is great. I feel like the player movement is a little slippery, it takes a while for the character to stop which definitely adds to the challenge.
Personally, I think if the character stopped almost immediately it would feel much nicer, but I do prefer snappy controls so this is subjective. I liked the idea too, having different ways to play the game is great!
