Hello,

here is my feedback for your game.

Things I liked:

• I liked the fact that you try to learn all the aspects about game design and developing your own models as well as code. Especially for indie games this is a great strength if you have knowledge in many aspect of game development.
• Since you are new to game development it is great that you chose a game idea that people are familiar with. People know games about dodging obstacles and things alike. That avoids unnecessary instructions as the game is straight forward. This is a good way to start learning how to make game.
• Game is fun for what it has to offer.

Suggestions:

• In the first level it is really hard to read the first instructions of the controls without hitting some obstacle. Consider pausing the game so they played has time to read the contol instructions or make the player move slower. I recommend the first one. 
• The music restarts whenever you die. I would make the music player scene independent and persistent so you can avoid having the same few seconds looping if they player dies alot.
• There is no purpose in collecting the energy balls since there is no highscore recorded. Collectibles need a purpose of players will not attempt to collect them all. Since you can use the sprint infinitely you could use the energy as the resource that gets consumed when you sprint. This both limits the duration the player can sprint and gives the energy balls a reason to be collected. Tracking the overall collected balls might also be a good feature for people to compare themselves. Time should also be tracked in a game like this.
• Some parts of levels are too linear meaning you don't have to switch lanes for a "long time". This comes does to playtesting more and making sure those areas get changed in your level design.
