The theme looks great in the game! There are some bugs during the game, such as the character being a few pixels away from the platform, the first enemy not attacking the player, and the player only defeating the enemy when the attack animation finishes. Regarding the blurry pixels... Game Maker also has this problem, I don't know if it's complicated to fix in Unity, but overall the game is very fun and really makes you want to finish it. The developer knew exactly where to make the game difficult.
