Woah, incredibly cool game!
I love the aspect of the color matching, as it seems very easy at the start, but it actually needs a lot more skill in later stages!
The movement aspect is really well blended into the gameplay, as you need to time it as well, after spotting the color, and the obstacles add to the skill ceiling.
The only thing I'd add, is a visible timer to be sure how time left you have. Other than that, a great time killer! Amazing job for your first game! :D
