The thing is that the way to win is to finish first in term of time, the thing is, how will the score of the osu player matter? plus, if its a race, the minecraft part can be interesting like any other minecraft event I guess, but the osu player has a time already fix, if he plays lets say the 5 maps of 5 minutes each for instance, well it will take him 25 minutes to finish his taks, not less, not more.
