That's fine for me since I use Libresprite :-)
I was just saying that sprite sheets and individual sprites are usually provided so they can be used in game engines. PNG is the way to go!
Keep up the good work
Oh great, it avoids having same buildings everywhere :-)
btw, I've just spotted an issue with 48x48 textures. The name is "Modern_Exteriors_Complete_Tileset_48x48.png" but it's actually a 16x16 tileset.
Older ZIPs were OK. I don't know when the issue has been introduced. I was still using an old tileset up to now.
