This is cool! I had a lot of fun playing, the controls are very smooth and I like the visual style.
While I was playing I was always tempted to run into the red objects thinking they would be a power up, even thought it's read it just looks similar to the other objects you're supposed to collect.
I would love to hear a few more random options for the sound effect that happens when you collect an object! I like when picking things up in successions generates a little melody.
Over all I liked this a lot, great job!
