 Blek is a 2013 puzzle video game for iOS and Android by Kunabi Brother , a team of brothers Denis and Davor Mikan . The player draws a snakelike black line that recurs in pattern and velocity across the screen to remove colored dots and avoid black dots . It is minimalist in design , features excerpts of Erin Gee , and takes inspiration from Golan Levin , the Bauhaus , and Japanese calligraphy . The brothers designed the game as a touchscreen adaptation to classic game Snake and worked on the game for over six months . It was released in December 2013 for iPad , and was later released for other iOS devices and Android .
