How does your game fit the theme?
This game has two phases: Calm phase and Storm phase. During the Calm phase, the player can move around certain interactable blocks. During the Storm phase, a chest monster will start to chase the player, so the blocks move in the Calm phase can play an advantage to the player here.

Did you write all the code and made all the assets from scratch?
The code, yes. Assets are all third-party assets and are referred to at the description of the game.
