I can confirm that the game works on Wine.
It's very short tho, with little graphics/sounds.
You start with a score of 0 and you must hit Kotu with a ball.
Ironically, it seems to overflow to -10000 when you hit him for the first time.
After he gets hit, he throws you an insult.
After he suggested i should get f***ed, i penetrated myself. It should felt good
The intro music is kind of lame, it's way too slow before it gets decent and there is no music in-game.
There is also no animation in-game.
On my Pentium Dual Core 2Ghz, the game is smooth (how surprising lol) but after i hit him,
it slows down severely before it becomes fullspeed again. yeah
Oh and it uses DirectX. Would have been much easier for him to use SDL2 instead.
I mean just look at the code x_x
