Please tell me the tile map effect algorithm name.
uh... Not sure if there is any name there tbh. Just delay each tile by the direction you moves + add a little bit of randomness. Otherwise you just move up tiles with some ease each frame:
if tile.delay < time then tile.z = tile.z * 0.8 end
You can download the .love file and unzip it (as it's just a renamed .zip) and see for yourself in rooms/Floor.lua, :getTileDelay method and :update
