Friendship Melody is a cross-platform, guitar-hero-like browser-based rhythm game with mobile and controller support. It's available exclusively on the MLP Forums, featuring 5 classic pony songs listed below:

Yes, those are my scores on all the tracks. I really don't like rhythm games and my performance reflects that

The game has returned for 3 weeks, lasting until the 11th of June (I sure hope that does not mean it will be gone forever after that). Alongside it is its corresponding event on the MLP Forums, which awards you an exclusive badge for completing the two new levels, those being "The Magic of Friendship Grows" and "Rules of Rarity," provided you have an account (as the game has the MLP Forums account system integrated into it) and submit your score in the comments of the event's thread.

Now, unless you're an active user of the site—meaning you probably already knew about the game—the badge is of lesser importance. But who knows? Maybe you’ll like it on the MLP Forums. An admin replied to me and had a casual chat with me via private messages immediately after I created my account. That’s some exceptional treatment for random users!

I did not intend to have two posts in the same day. I became aware of this game like, right now, and it is honestly pretty dope. That's it.
