as far as I know, they are making a lot of changes and adding things on the gambling site, perhaps once they are done with those they'll start on marketing again and probably promotions, bonuses, tournaments, etc...(not really sure if they already have those) to attract gamblers to their gambling site.
I agree with you, I also think that they are putting huge effort to improve their site, its design and also they might be working on some new games. The developer of the L0tt0 is a quite hardworking person and he's highly devoted to improve that site.
I'm very sure that once development and design work is fully completed, the owner of the site may start doing some investment on advertising activities once again. It's quite a tough job so it'll take him sometime but I hope to see some good marketing of this site.
