I've recently started learning 100%, and doing TAS videos, but it doesn't seem like there many people playing anymore. M2K2 seems all but dead. Seems sad.

If you look at the timestamps on the leaderboards you will see that there are a lot of recent submissions. The game is somewhat inactive at a high level but in general the community very much still exists.

However, you are correct that m2k2 is dead (rest in peace).

I agree in saying that the community is here, but what you can see looking at the leaderboards don't exactly reflects how active is the community. I mean some people (including myself) play very regularly this game, but can't beat their PB, giving the impression that they stoped playing, which is not always right
