Pandaland (download page) is a short 2D platformer created by Svante Danielsson using Game Maker, with music and level design contribution provided by Jonas Eriksson and Nils Vaernö. There are only four levels to play, but credits should go to the developers for keeping the adventure short enough without overstaying its welcome. A challenging hard mode is also revealed once you've beaten the one and only boss encounter in the game.

Being a Game Maker production, you can switch between full screen and windowed mode using the F4 function key at any time. (more info)
