This is an addon now released for Amnesia: The Dark Descent. It allows you to play as your choice of one of the 6 main characters of My Little Pony in both the campaign as well as custom stories.
This demonstrates the Twilight Sparkle and Applejack soundbytes released in version 1.0 as well as the new running sounds that adjust to floor material. Shown in the video are examples of dirt, rock (original sound), wood, shallow water, deep water, and one example of a tileset with reverb. VGparastar1 is takes sole credit for these - and yes, there are sounds for every other material (organic and metal for instance) I just didn't put in any examples.
