I received much feedback for my game. One of the common problems players had is that sometimes collisions could be too brutal. So I added some invulnerability time after the collision with obstacles. Don't worry, the game is still challenging, after your hit you have to think quickly, or you meet your second obstacle.

Make Electron happy, like on picture below. Play the game, rate it and leave your feedback:
