The gameplay consists of reaction-jumping across rooftops in a randomly generated level. There are several different 'patterns' of houses to give a varied experience. On top of this, there are a few ways to get points. The first is to just travel as far as possible! The second is bonus points for every present delivered. Santa will drop a present every time he lands on a roof, so this encourages the player to hit as many roofs as possible, instead of just skipping them and soaring over as large a distance as possible. The third are small pickups that occur randomly. These pickups (glasses of milk and cookies!) give a large amount of points when obtained, and occur in between houses.
All in all, this was a fun little project, and ended up being a game that's pretty enjoyable to play. It can be found on the Windows 8 Store, as well as itch.io for standard desktop computers.
