Platypus

The player flies an antiquated spacecraft (the last of the fictional F-27 Platypus fleet) and attempts to defend the peaceful country of Mungola from neighboring Colossatropolis, which has become so overcrowded that its inhabitants are taking over Mungola for space and resources. The game consists of four levels, with five areas per level and a strong boss enemy that must be defeated at the end of the fifth area. The player can collect power-ups that affect the type and firing rate of the ship's weapons, equip auxiliary cannons, or double the point values of all enemies and items.

Points are scored for destroying enemies and collecting bonus coins and fruits. In addition, at the end of each area, the player receives bonus points depending on the percentage of primary targets and enemy craft destroyed. One life is lost whenever the player's ship collides with a target or is hit by enemy fire.

All the artwork for the game was created using a process called claymation. Flack has stated that due to limited availability of plasticine in his local area (at the time the game was created), he re-used the same lump of grey clay to create all the models, photographed them with a digital camera, and coloured the images in Adobe Photoshop.
