Degrees of Separation - Finale and Endings
The finale for Degrees of Separation and both endings (3:10 for the final choice, 3:51 for returning to their worlds and 5:04 for remaining together). Not sure if anything extra occurs for finding all the scarves. The separation ending is the same whether Ember goes through her door or Rime enters his.
This is a pretty fun little game that reminds me a bit of Seasons After Fall with the environment manipulation. It's not very long (though solving all the puzzles to collect every scarf might take a bit more time), but if you like puzzle platformer type games it's worth taking a look at or buying during a sale. I'm not particularly good at these sorts of games but enjoyed playing through the story. The music's quite good too.
