kiki the nano bot is an open-source puzzle video game designed by Thorsten Kohnhorst and first released in 2005.

[7] Gravity works towards the surface you were last touching and kiki can walk around the walls and on all sides of any block.

[8] The game has 50 levels, which can be viewed by selecting "Statistics", in the main menu, in which the progress of the user appears.

It was designed by Thorsten Kohnhorst, who began work with such a tight deadline because he was participating in the 2002 uDevGame contest.

In order to avoid his game being a copy, he had the character move on the inside walls of a room instead of on free-floating platforms.
