Did you have a look at the demos/collide sample that ships with pico8?
Is that what you are trying to achieve?

Super simple example:

function _init()
  x,y=0,0 -- actual sprite position
  new_x,new_y=0,0 -- position to move sprite to
end

function _update()
  if btnp(1) then -- 1 == right
    new_x+=8
  end
  if new_x>x then
    x+=1 -- moves one pixel per frame
  end
end

function _draw()
  cls()
  spr(1,x,y)
end

For more directions than one, make more if tests, or perhaps a lookup table with btnp() mask values to see where you want to move based on them. You'll need to make sure you can't change direction midways in a move, because then it won't keep to the grid anymore.
