Short and pleasant platformer! Made me smile, I love little romps like this. One issue I had was on the 2nd room, I didn't know where the 'checkpoint flower' was, so the barrier at the end of the long flying segment was closed. Making the checkpoint flower a tiny bit more obvious (like one pixel bigger) would have probably solved that. Otherwise, the use of music to convey the platform timings was great, and I particularly liked the choice of colors. Great stuff!
