Kiki the Nano Bot

Kiki the Nano Bot is a freeware, open-source puzzle game with 3D graphics, described by the developer as a combination of Sokoban and Kula World. Players control Kiki, the only machine remaining fully-functional in the Nanoworld after a parasitic component incapacitated the Maker device, traveling through its mechanisms in a quest to fix it. Kiki can be moved around the levels in all directions, rolling around with two adhesive wheels that attach to the available surfaces, changing the room gravity to where it stands. The little robot is equipped with a laser gun that has to be used to destroy obstacles and activate switches.

The main objective of each level is to reach the exit portal. In some rooms, the portal has to be activated first by shooting the switch. Later puzzles add new features, like blocks that have to be moved out of the way, platforms to jump and land on higher places and a series of gears that must be positioned and connected in a chain, to start a generator and give power to the portal.
