I just tried the demo and fell i love with it, but where i live i kinda have some problem buying in itch.io and is more easy to get stuff through Steam.

Thank you, we are working on Steam support, but it has been delayed and will take some more time.

DLsite is one of the web sites where LovelyComposer can be purchased overseas. Is it possible to access it?

(Are there a lot of people in the world who can't buy on itch.io?)
