Thanks. It's a game that's not finished yet. It's a sports game (you have to throw the javelin, run 100m cycling,etc) The problem is that the story and instructions are in Spanish (I'll upload an english version in the near future). So I'll tell you here how to play:
Javelin: (right arrow key to start running, then down arrow to pick power ups only once in eac one, finally space bar to throw the javelin)
100m: press "M" and "N" as fast as you can. If you control player 2, use "2" and "3"
Cycling: you control it with the arrow keys (up is for pedaling, but then you can sprint faster using M or 1, but this tires you)
if you want to play using player 2, then you use wasd and you sprint using "R".
