Jaroslav Kolář is a Czech video game designer and producer. In the early 1990s he enjoyed playing LucasArts adventure games, especially and Monkey Island I. While studying at the secondary school Gymnázium Slovanské náměstí in Brno, he met programmer Petr Vlček and they together created a parody of Monkey Island where Guybrush had to escape from an island inhabited by donkeys. His opponent was LeGek, a brother of LeChuck. Petr Vlček at the time only had an 8-bit Atari 800 and therefore developed the game editor and engine at school. Jarek drew the locations and wrote the plot. While on a school trip to Polička, Jarek decided to skip a lunch with his classmates and instead went to find the panelák where entrepreneur Petr Vochozka lived at the time. Two weeks later, Vochozka saw their demo and agreed to produce and distribute the game. The Secret of Donkey Island, released in June 1994 after two years of development, is considered the first Czech commercially successful point-and-clickgraphical adventure. In the following months Petr Vlček and Jarek Kolář created an adventure game called Seven Days and Seven Nights, based on a story about a womanizer written by Petr Vochozka for a semi-developed Amiga game. After working for a while for German game development companies, Jarek Kolář and programmer Michal Janáček founded the company PTERODON, s.r.o. in October 1997. In May 1998 they started development of a new 3D game, released in 2000 as Flying Heroes. Thanks to Petr Vochozka, who in 1997 founded with Jan Kudera Illusion Softworks, Hidden & Dangerous was successfully released in 1999, and was followed by Flying Heroes in 2000. Both were distributed by Take-Two Interactive. Pterodon closely cooperated with Illusion Softworks; their teams shared one open space in an administrative building in Brno. Jarek was lead designer of the tactical first-person shooterVietcong, released by Pterodon/IS in 2003. One of the last released games Jarek contributed to is Mafia II. Kolář later joined newly formed Hangar 13 and contributed to Mafia III until he returned to the Czech Republic and joined Bohemia Interactive. He also worked on a story for Dead Effect and Dead Effect 2. He currently works for BadFly Interactive.
