That's a neat little concept, although the game seems unfinished, or bugged? At one point walking right just results in an endless darkness, or the camera freezing in one spot.
You should definitely find someone to proofread your text for spelling and grammar, or use an online service. It doesn't take long, and would improve the overall perception people have of your game. Same for how text is presented in game: the first character's line was extremely small and hard to read when playing in browser, and the line with "PLEASE GO TO THE TALL TOWER" just disappeared way too fast.
Overall not bad for a first project!
P.S. Some links in description for music sources are broken, although you should be able to fix the description through "Edit game" page.
