Fishing Cactus has just released Equilibrio Lite Edition [App Store], a free version of its gravity-based game which challenges you to get your ball to the end goal by navigating ramps, trampolines, spikes, and more.

While the premise of the game may seem familiar, the game incorporates a number of twists to keep it interesting.  There are 5 types of balls, each with different properties and gameplay characteristics. These include rubber, glass, steel, stone and paper. Levels include obstacles such as spikes and acid that destroy the balls on contact. Tilting your iPhone will allow you to build up momentum to jump obstacles and avoid danger. Part of the challenge, however, is also avoiding shattering your ball, so proper control becomes a major issue and you can't just speed through each level.

The lite version offers 15 of the original's 60 levels and only the Conquest play mode, out of the original's three avialable modes
