Mofu has also developed Fuju Hime: Cursed Futana Ring, which you can purchase here:
https://tempoko.booth.pm/items/378803
The game is a turn based strategy RPG, similar to Fire Emblem or XCOM
This version has less mosaic filter than the DLsite.
Mofu-san has stated he would like to release this game on steam uncensored with added content and an official English translation.
Sorry, not quite sure I follow the question. If you mean the difference between Fuju Hime on booth and DLsite, the difference is DLsite has more aggressive censoring than the version on booth. Other than that, the 2 versions of Fuju Hime you can buy on either digital stores are essentially the same game.
If you mean the difference between Futakin Valley and Fuju Hime, Fuju Hime is Mofu-san older game released a couple years ago, which contains different characters, scenario and 44 CG event scenes. The gameplay of Futakin Valley is more of an action adventure metroidvania style game, similar to Hollow Knight or Metroid.
While Fuju Hime one the other hand is a turn-based strategy game, similar to Fire Emblem and XCOM. If you're confused on the difference between the 2 genres, you can look at the gameplay examples of Hollow Knight and Fire Emblem to see how different both games play.
Also, Fuju Hime is currently a fully completed game that is currently on version 3.40A and available to purchase, while Futakin Valley is still incomplete and hasn't had a proper version 1.0 fully completed game release yet. Hope that clears any confusion regarding your question.😁
