First off, stop acting like a idiot with the whole '....help me.... *gasp*...*wheeze*' thing.
Second, on the main menu of Blockland go to Options. At the bottom left of the gui, set Texture Quality, Particle Quality, and Shadow Quality to Minimum. Then go to the Advance section, and set the Draw Distance at or below 0.500. If the lag is still so bad that you can't really play, then either set some things lower, or get a better computer.
This is what I do with my laptop, and I get little lag. But the game doesn't look as good as it would before hand.
