Nice casual game.
For feedback: having the character move toward the camera made it a little difficult to time jumping over obstacles. I generally jumped too early since the depth perception was hard to know how close obstacles were to hitting me. It seemed like some of the audio sound effects didn't play each time (like hitting obstacles or jumping and having the skates land), even through I could here them sometimes; may be related to how many audio sources you used, Play() vs Play.OneShot()?
In most cases, it was just easier to move aside (based on jump timing comments above). There wasn't really any incentive to use jump versus move aside. A score system could help here, but I don't know if that's the best idea because I did like the casual vibe of the game.
I thought the art style, color palette, and background music all worked very nice together. I liked that you had a menu button that could be accessed at any time. This was helpful because on first playthrough the obstacles stopped showing up...even though my character was flashing from hitting them; so I had to restart.
Great start!
