Hey, PlayerXT here! I just came by to take a quick look at your project, and I have to say that the parallax effect and the shaky camera have really brought the game to life.
Oh, and just an idea I thought of while I was testing it. I don't know what you're planning with the player movement, but you know how the character can infinitely jump on the wall, and what if the character stuck to the wall every time they used the pickaxe, as if they were using the pickaxe to climb walls? I think it would be an interesting mechanic, but it was just an idea that crossed my mind.
