A bit of a niche interest, but I've knocked together a small (25-room) pony-themed level named Harmony for the retro-style 2D puzzle platformer VVVVVV. Nothing fancy like custom graphics, just a bunch of rooms inspired by stuff from the show and the fandom. Think of it as an alpha version -- it's playable, but occasionally you'll get stuck in a wall and need to save and restart. Harmony is a fair bit easier than many third-party VVVVVV levels, partly since I got fed up with the majority of those being almost impossible for those of us without ridiculous levels of gaming skill. You can get the Harmony level here, for the next few weeks at least: [link removed, as my browser has started flagging it for adware. PM me if you want the level!] It definitely works with the full version of VVVVVV, and should also work with the free Make and Play Edition, which is available from the makers here for Windows, Mac and Linux: http://distractionware.com/blog/category/vvvvvv-make-and-play/ A couple of screenshots to give you an idea: Spoiler: Two of the 25 rooms in "Harmony"
