Very nice game and theme interpretation. The artstyle of the main character looks cool, the animations are very cool too, but I feel like you need to make each stage more cohesive with the pixel art style of the player. Also, some polishing for player actions would be nice (for example, make the player slide less on the ground, make its jump adjustable based on how much you hold the jump button, implement classic platformer game-feel features like coyote time and jump input buffering, ecc...).

Here are a couple of issues I ran into while playing the game, with also some suggestions on how to improve it:

1. The pause menu bugs out when you press buttons: it doesn't do anything, and then you get stuck on it (so probably Unity throws an error and the game basically freezes);
2. I didn't really understand what the goal of each level was: in level 1, after getting bigger for the second time, I got stuck... Maybe the goal is to collect all coins, but in this case, don't make coins the player already collected respawn in each level when you restart with a bigger size, and add a UI indicator with the total amount of coins collected for each level while you play;
3. Instead of having a "play" button that sends you to the first level (and redirecting the player to this menu every time he dies) maybe you could try adding a level selection screen after the user presses "play" (instead of having a separate "select level" button), and maybe send the player back to this level selection screen when he wants to quit a level with the previously played level already selected;

The game was fun overall, most notably thanks to the animations of the player (I love the idle animations), good job, don't stop making games :D

A good minigame, clever idea

animations the great , there's one problem: сharacter sprite is cool, but the envinronment is not matching to a character sprite and this feels some strange. 
uhh can you rate my submittion?

Love the character animations! :>
