Explanation:
-- instruct the pico8 to use the second palette, for the top half of the screen only
poke(▒|▤,웃/●)
memset(81-😐,170,8)
-- save space by encoding the memory address for the display
s=●-웃
-- set both palette one and two
pal({0,0,-15,1,-4,12,13,12,-4,1,-15,1,-4,1,-15},1)
pal({-15,1,-4,1,-15,1,-4,12,13,12,-4,1,-15,0,0},2)
-- clear the screen
cls()
-- save characters when calling rnd
r=rnd
-- mark the start of the draw loop
::_::
-- random position for x
x=r(128)
-- random position for y within narrow band
y=r(16)+56
-- draw pixel of random color at that position
pset(x,y,r(16))
-- choose a position in the display memory
d=r(8191)
-- the part that makes the "city"
poke(
s+d-tonum(btn(4))*0.5, -- write to this position, if the button is pressed shift by -0.5
@(s+d-64*(mid(1,(r()-.5)/0)*2-1)) -- peek @ this position, last part is to get 1 or -1
)
