Reclaym is an innovative, interactive teamwork and brainteaser-style platform game for older kids / teens where you must guide a bear made of clay through a series of side-scrolling, obstacle-based levels. The soft, malleable composition of your jumping bear hero character means that he can perform specialized tasks such as flipping switches or opening doors that allow him to progress. For example, he can be split into two in order to hold down extra switches, or flattened into a pancake shape in order to squeeze through tight gaps, and more.

Background info: You play the role of the former ruler of ‘Claytonia’. Having been ousted by the evil Lord Claymore, you must find the remaining pieces of yourself by progressing through the various traps and obstacle-filled levels laid out by Lord Claymore.

Sling is a tricky, physics-based platformer and game of skill where you control the acrobatic movement of an elastic, ‘sling-able’ green slime ball. In each of the 50 increasingly-challenging levels, you must fling this friendly slime ball character (called Sling) to multiple ‘ledge grabs’ in order to open a ‘Vortex’ which you can then escape from!
