Moon Walk

Quite a fun and simple game, but there are a few things you need to polish in order to make this game interesting -

• The obstacles are getting mixed with the background stones placed on land which is not a good thing as per Game Design as this is confusing the player based on level design fault, not the actual game. 
• The speed of the player is increasing so abruptly that the user can clearly notice it by seeing the jerk which seems really odd.
• Also, sometimes the speed of the player is increasing In odd positions,  just when the obstacle is near to the player.
• Consider connecting the sound of jumping only when the player jumps, not when the player hits the button as sometimes the player is not ready to jump out, still the jump sounds plays. 
• The floating animations and the jump movement suit the game well., here you can consider adding some more obstacles to the game to limit the player from the sky too. 
• Gradually increase the speed using some Tweening or lerp.
• Improve this game by adding many more features to it in terms of obstacles, powerups, different movements, etc.
