Oddboy co-founder Ben Markby (27) was born and raised in Dunedin and opened a gaming studio in Auckland in February.
He knew he wanted a career in game design since his time at John McGlashan College.
''In my final year at Johnnies, I gave up on all subjects except design and I haven't stopped doing it since.''
Over the past three months he had created the mobile game Jrump with his business partner Tom Bellamy (24), of Auckland and staff from gaming studio Apparcanum Ltd.
The game is set in 2017 and new president Donald Jrump is running the White House and the world is in ruins.
In the three-level game, the player builds a wall to allow the new president to climb to outer space and ''make the galaxy great again''.
''It's a bit of stress release because you get to take Donald Trump off Earth,'' Mr Markby said from his Auckland studio yesterday.
As the player builds the wall, the president faces off with Mexicans, global-warming scientists wielding books of facts and jet-pack wearing characters resembling politicians Hillary Clinton, Barack Obama and Bernie Sanders.
If the player fails to build the wall high enough, the game ends with the president falling to Earth shouting insults, such as ''weak'' and ''loser''.
In the game, players could ''unlock'' a character based on Workers' Party of Korea chairman Kim Jong-un.
Since the worldwide release on Friday night. the game had been downloaded about 20,000 times on iOS and android operating systems.
''It's quite promising.''
He admitted ''a dark part'' of his psyche was curious to learn the fate of the world if Mr Trump was elected.
''I don't want to see it but it's like seeing an accident and you can't turn away.''
