hello Gazielle, the files only work in unity or in game maker too?? do you have the sprites to make the maps with the theme of each one or is it just the backgrounds??
Hello! Sorry for the late reply I didn't see your message.
The unity package files is only usable in Unity but all the sprites are in the .zip file so you can use them in game maker if you want!
Unfortunately I didn't make a tilemap to go with these, they are just background with a floor for your character to walk on.
