This is an empty base-cart for you to make your own levels
it's still pretty rough, but for now it'll do

• Multi-Cart
  the bosses of IWBTG are GIGANTIC in sprites AND code. the next step going foward is to separate the bosses and heavy rooms(tetris) into their own carts that way we will be able to afford more accurate bosses without losing too much(only that cart loading time)
• Better Menu
  the game's menu is pretty basic rn, i plan on separating it into it's own cart and do some cartdata wizardry so that we have different saves and continues(i don't think this will be hard, just time-consuming)
• Level Loader
  as of now, the levels are taking a good ammount of map data, but IWBTG is a HUGE game and it won't fit whole into a single cart, the plan is to divide the map into sections and load these into the map memory as they're needed, but the method to do so is still being looked at as idk if i will have enough chars(or tokens lol) to do it the usual way once the whole game's code is in there, and i don't want to just multi-cart it.
• Friendlier code
  my code is a mess. i'll divide and reshape the code so that it's easier to understand and make your own levels while the base-cart isn't here
• Mike Tyson's Theme
  it's missing ;^;
  

1-Pick a beat

Choose a song from the 8 options with different style and speed to set your difficulty

2-Pick a pic

Choose a picture from the 48 available, they come in 3 sets: 8x8,harder 8x8 and 16x16

3-Paint!

Hit the notes as they get to the pointers, you can set your controls on the main menu:

Control scheme 0:

• Directional - Yellow
• Z and X - Blue

Control scheme 0:

• Z,Down,Right - Yellow
• X,Up,Left - Blue

4- Medals

If you get 100% you get a medal depending on your difficulty

	[0x0]

	[0x0]

  for i=0,17 do
   local posx, posy = ((point+i-2)%imgs)+imgp.x,imgp.y+flr((point+i-2)/imgs)
   if i==17 then
    if sget(posx, posy) == 10 then --is  yellow
      scrbuf[i] = 1
    elseif sget(posx, posy) == 12 then --is  blue
      scrbuf[i] = 2
    else
      scrbuf[i] = 0
    end
   else
     scrbuf[i] = scrbuf[i+1]
   end
  end

we also update the pointer every 2 beats of the first sfx channel using stat(), this way the speed of the pointer follows the speed of the song (this method could be used to follow odd time signatures/rhytms by using %3 for example)

  c2 = c1
  c1 = stat(20)
  if c1 != c2 then
    if c1%2 == 0 then
      point+=1
      readspr()
    else
      return false
    end
  end

if we press a key we check the buffer at the right spot to check if you got the note right
if so, we paint a dedicated piece of the spritesheet with the right texture and set the buffer with a "empty" note
if you press a wrong note, we also paint it with the texture but with offset colors, and put a "wrong" note on the buffer
if you press on empty you paint the texture and set a "not empty" note

 if inpa then
   if scrbuf[2] == 2 then
     sset(imgx,imgy,sget(posx,posy+imgs))
     scrbuf[2] = 10
   elseif scrbuf[2] == 1 or scrbuf[2] == -1 then
     sset(imgx,imgy,(((sget(posx,posy+imgs)+1)%15)+1))
     scrbuf[2] = -1
   elseif scrbuf[2] == 0 then
     sset(imgx,imgy,sget(posx,posy+imgs))
     scrbuf[2] = -3
   end
 elseif(...)

Once the song ends we just check the score textures and keep count of the errors
if black, is the end texture black?
if B or Y, is the end texture and img texture the same color?

for i=0,imgs*imgs do
    local imgx, imgy = ((i)%imgs)+112,flr((i)/imgs)
    local posx, posy = ((i)%imgs)+imgp.x,imgp.y+flr((i)/imgs)
    if sget(posx, posy) == 0 then
      if sget(imgx,imgy) != 0 then
        errors +=1
      end
    else
     if oneb == false then
      if sget(imgx,imgy) != sget(posx,posy+imgs) then
        errors +=1
      end
     else
       if sget(imgx,imgy) != sget(posx,posy) then
        errors +=1
       end
     end
    end
  end

and to do the medals you just peek and poke at the designated hex

and that's basically the whole mechanic, to create "expasion packs" it's just a matter of drawing over the textures, or creating new music but i've drawn too much already lol

• removed "ghost notes" when replaying a pic
• removed bug where perfect would stop registering if you "End Run" then exit
• overall code optimization of 222 tokens

V1.3 even more optimizations

• fixed bug where it wouldn't save more than one medal per session
• more code optimization of 213 tokens
