This game is definitely a good concept for mobile and I like how you included a shop so that players have a reason to keep playing the game to get new upgrades or trails. The animations for attacks like laser bunnies are clear and give the player enough time to dodge. Some critiques are that it should be clear what purchasing "power ups" does, I thought it would give you the powerup in your inventory next time you play but it wasn't clear that it would actually upgrade that power up. It also isn't clear how many upgrades there are. Also changing the environment in the background would be nice to show visually how far the player got in a better way than just a number like high score.
