Somewhere around 2001 I got a job at Formula, a games department under the Lost Boys flag. They had already produced a few titles and were currently working on Black belt challenge, a fight game for the Gameboy Advance. I worked together with Mathijs de jonge (game designer), Ferry Spiering (coder), Dennis Zopfi (game designer/artist), joris de man (musician), Casper van de Heijden (coder), Michel van Elk (coder) and Arjen Bokhoven (artist).
One of the trickiest part of the game was the code which had to figure out if (and how) you were hitting the opponent. Depending on how and where you hit the number of points and the effect of the blow changes. We also had a computer player, which given these tables had to figure out in a non-computery way, what to do next. Tricky stuff
