Cool game!
I appreciate the extra effort you put in to make this a little more than just a Flappy Bird clone. The star and the coins are great ways to spice up the gameplay; It was quite relieving to find out that they increase your score if you get them. Along with the invincibility buff, it would be cool to introduce more obstacles to avoid too, like maybe something that temporarily speeds the tubes up, or something that increases/decreases the gravity. You could even take out the endless runner aspect and make a level system to reduce the similarities to FB if you wanted that.
Also the music is fire, I left it on and I'm listening while typing this!
