Great art/visuals. Definately needs sound to enhance the experience. Simple concept of combining colours to create the right colour to exit the level, I think puting a level timer on which gives players a limited time to find the flowers would be fun. Controls needs tweaking, I didn't feel totally in control of the player at times. Also perhaps a level system where your character doesn't know all the types of flowers and needs to unlock them before they become visable? I'm just thinking out loud really. Great job.
