    Hello to all the players who have been eagerly looking forward to Kaiju Girls! We would like to share with you the latest updates regarding our project’s progress and revised release schedule.First and foremost, we sincerely apologize.

    Updates and Delayed Release of KaiJu Girls

    To all the players out there following the development progress of KaiJu Girls... Howdy! Today, we'd like to get everyone up to date on...well...the latest developments! We've been working our stinky butts off to ensure that the game is of the highest quality and is packed with tons of fun content. Here are some of the exciting updates players can look forward to: 1. More character visuals and CGs: We want the game to be a veritable feast for the eyeballs (and other body parts), so we're adding even more character visuals and storyline CGs. We think this'll create a more vibrant world as well as spice up the story. {STEAM_CLAN_IMAGE}/43299216/2f438a490371d9ee5a60c45b0f885d51d113c271.jpg 2. Refined movements and "director's cut" content: We've heeded your requests and are packing this puppy with tons of dynamic scenes and pics. This includes dynamic character visuals as well as CGs, all of which will liven up the game's feel. Besides this, we're adding a "director's cut" function for Karasu Chan's CG variations. You'll be able to turn it on or off in the settings. Turn it on to check out Karasu Chan's truly original, juiciest take on KaiJu Girls. {STEAM_CLAN_IMAGE}/43299216/a209cfc1abe66205b19bda746ddac9e603c59559.gif 3. Kickass story events: We really want KaiJu Girls to have a well-rounded, deep storyline. And to help achieve that goal, we're creating plenty of events and side stories. Choose your own adventure! A single choice may lead to a completely different ending. {STEAM_CLAN_IMAGE}/43299216/1e90afb4d58d3499c6d4449405979ae0d4a3caae.jpg 4. Chinese and Japanese voice acting: That's right! To enhance the game's atmosphere, we're recording the game in both Chinese and Japanese. We can't wait to see (and hear) how realistic and emotionally compelling each version will be. 5. Original soundtrack: To truly bring this world to life, and to ensure the story is as thrilling and exciting as can be, we set really high standards for the game's soundtrack. This OST is gonn...
