Nobody cares but random lvl 0 improvement
The highscore is measured by how many tiles you pressed down so it implies being fast. It would obviously not be a long run and its not really a "speedrun" but for example crazy taxi long jump is also not a speedrun. Honestly i just want an official ladder for this category because thats all i play from time to time and i feel like i got the wr :D
I think having a B-Type (25 lines) category would be fun, we could either run for time or Highscore. Highscore is also measured by how many tiles someone pressed down, so it is kinda bound to time too.
