Reach for the skies!
Penguin Jump is a work in progress game from Grindhead Games, the authors of the PhaserLE game editor.
All you need to do is see how high you can get, while avoiding all the nasties that tumble down! Interestingly the floor is made up of about 10 tiles. A floor manager caches positions into an array, allowing for an endless level that can be traveled forwards and back through with little overhead.
