Oh I'm sorry about! Something most have gone wrong when I exported the sprite sheets (I probably selected the wrong file format). I'm going to fix it right away. Thanks for letting me know!
I went ahead and added all tiles, objects and backgrounds as separate images! Please let me know if there is anything else I can do make it easier for you or other people to use the tile set :)
Thanks! I'm planning to expand the pack to have different themes. Cemetery is just the first one :) Good call on the contrast! I'll fix that right away.
