It can be run on recent Ubuntu distributions and includes all of the new levels in the recent Android and Windows Phone 8 updates. Controls are all keyboard driven with the same controls as Invertical, so arrow keys with space and ctrl for jump and switch.
For those unfamiliar with Trick or Treat, it is a puzzle platform game where you need to switch between the world of Trick, which is full of nasties and enemies to avoid, and the world of Treat which has items that you'll need to collect. You'll need to figure out your route, switching colour between the two worlds as you go.
Installation may be a bit fiddly so if you've any feedback, let me know!
