I really liked the music, and the pixel art and background are very cute and fit well together.
Unfortunately it seems like the build is bugged and no forks spawn, and the game window is too large to fit in a standard monitor window. The vertical orientation of the game could work but the resolution would need to be scaled down in the build (This can be done in Unity with File>Build Settings>Player>WebGL Tab>Resolution and Presentation). You may also want to double check your game output resolution in the game window of the Unity Editor, which you can base your build output resolution on for WebGL.
Good effort though! I get the sense there was some difficulty setting up the WebGL build (I see that 1 minute 40 second before deadline submission haha), and I've definitely been there! Keep at it, and I look forward to seeing more from you in the future!
