Nice work this is a good start. I like the voice and style of the writing and the focus on friendship as a theme. It seems like the choices don't ultimately effect the outcome of the game, it might be interesting to create different endings depending on some of the choices made throughout the story.
You have this set as a downloadable, I was able to download the HTML file and play it, but it should be set as "Play in browser", you might have skipped that step in the instructions, you can still edit the page and set it to play in browser.
