You can create animated tiles in Pulp, if you want to make a scene less static. However for fully animatated scenes, it's a bit trickier and will take a lot of tiles depending on the size. The general idea is to take an image (equal or less than the size of the screen), split them into chunks and place them into a room. There is a tool for aseprite that lets you import large animations into pulp.
You can create a couple of loops that place the tiles from top to bottom without having to swap every tile on screen manually. There's a much comprehensive guide on how to do this with imported tiles but it's something like this, it draws all tiles on screen.
x = 0
y = 0
tile = 0
while y <=15 do
while x <= 25 do
tell x,y to
swap tile
end
tile++
x++
end
y++
end
