Theology, sea, child and me

An assignment of Game Design. PS: Because the bug happens while building WebGL: warning: 2 FS.syncfs operations in flight at once, probably just doing extra work cannot be fixed (and I indeed cannot find any solutions online to fix it), in this game you cannot destroy any PIN door. Which means, you cannot play it. So you can only watch my video. I am so so so sorry. Is there anyone can help me fix this bug?
