FlipStar Sirens is a point-and-click adult game by Linksign, made in Godot with 2D AI CG artwork. Its premise follows a world changed nine months earlier by The Event, which gave special powers to selected women and sparked panic, confusion, and a search for answers. A disgraced former senator, Margaret Rossum, promises a solution to anyone who wins her competition; you play as a participant, though the players are actually pieces in a game older than history. The tone leans toward parody.
The current build is v0.80, dated September 17, 2026, and development continues. It runs on Windows, is in English, and is uncensored. The update adds a gallery unlocked by winning thirty matches with a character, a hidden character tied to the Strongest in the World achievement, and a Terminal containing more than ten thousand words of extra story. Terminal access is linked to the Freedom and Passion achievement, while Structure and Beauty opens higher clearance entries. Most achievement requirements were reduced, hidden characters now get bios and theme songs, the tutorial was clarified, and notifications better show when AI abilities activate.
Developer's description
Nine months ago, The Event changed everything, giving special powers to select women across the globe. The result was panic, confusion, and a quest for an answer. Disgraced former Senator Margaret Rossum has offered that answer to anyone that wins her competition. Little do they know they have simply become pieces in a game that has been played for eons.
v0.80
- A gallery has been added. Win 30 matches using any character and their individual gallery unlocks. No achievements or codes needed.
- Added a new hidden character, unlocked with the "Strongest in the World" achievement.
- Added the Terminal, which contains over 10,000 words of additional story. It's unlocked with the "Freedom and Passion" achievement. The "Structure and Beauty" achievement unlocks higher clearance terminal entries.
- Most achievement requirements have been cut in half (or more) to reduce grinding.
- Bios and theme songs added for hidden characters when they unlock.
- Tutorial has been reworded to better clarify game rules and abilities.
- Notifications have been added to better indicate to the player when the AI has activated certain abilities.
- Fixed an issue where the ability panel would stay up and block the board.
- Fixed a bug where Navi's ability wouldn't work if she was used to activate ToxicCupcake's ability.
- Fixed a bug where it was possible for ToxicCupcake's ability to relocate her in the same space as Boris.
- (Hopefully) finally fixed the bug that was resulting in the AI opponent skipping or taking extra turns.
v0.70
- A tutorial has been added to explain basic game flow and abilities. There is a new achievement (and award) for completing it.
- All of the "concept" sections have now been added. They are unlocked with achievement codes from "Earth, Fire, Wind, Water, Heart", "Latina Heat", "Flexible", and "Supergroup".
- In options, you can now load saves from a previous version. Currently, all this does is carry over achievement progress, so you don't have to restart your win count from zero.
- AI Aiko behavior adjusted to better judge when to use Yuki.
- Fixed an issue where Sheila's teleport would cause a bug if it interacted with Vesper or ToxicCupcake's ability.
- Fixed an issue where certain achievements weren't tracking correctly.
- Fixed an issue where Isabella's flower icon would block stat values.
v0.65
Mostly a bugfix update, with some quality of life changes. Big content additions planned for 0.70.
- Overhaul to the draft screen. It's now a carousel menu where the card values are easier to read and all abilities are explained.
- Nadia's ability nerfed so that she gets a random assortment of two relics every match, instead of all four being available.
- AI Eka adjusted to prioritize stronger targets.
- Visual "drone" indicator added so it's made more clear when Eka uses her ability.
- Anatomy corrections made to some CGs.
- Volume adjustments on certain ability SFX.
- Fixed
37
different bugs related to Vesper's ability. Yes, 37. And I didn't get all of them.
- Fixed a bug where ToxicCupcakes's CGs didn't show (again).
- Fixed a bug where Dakota's ability would sometimes require her to flip a card before activating.
- Fixed an issue where Teuila and Nancy were wasting their abilities to protect safe cards.
v0.60
This version introduces a huge gameplay change - abilities.
- Each card now has an ability. Hovering over a card in your hand will give you an overview of their ability and when it can be used. Some are automatic, others require activation or specific conditions.
- Complete AI overhaul. Previously, the opponent only cared about immediately going on offense. It now considers defense and card abilities. You'll find it's less aggressive, but more satisfying to play against. A lot more work still needs to be done.
- The cards actually flip now. The title of my game is no longer a dirty lie.
- First pass of SFX implemented for card flips and some of the abilities.
- The AI now "drags" cards instead of them just teleporting onto the board.
- The "open" rule no longer applies by default and AI cards are now hidden.
- Fixed issue where Na-Rae's song wouldn't play after 0.55 update.
- Aiko's cart art changed.
- Dr. Grant's card art fixed.
- Janie's card art changed.
- Katia's card art changed.
- All achievements now give out codes. Codes now remain on the screen.
- The only codes working right now are for the three extra cards. All other codes are prospective, meaning they will be valid for future unlocks that haven't been implemented yet. The code you get here will work in a future version. You won't need to do the achievement again.
- Added some fun secrets.
NOTE - Because I've had to rewrite a lot of the game to account for these new systems, please expect EVERYTHING to break. A lot of these abilities interact with each other in ways I can't predict and games are much more chaotic now (in a good way). If you find a bug, tell me what you did and I'll try to replicate and fix it.
v0.55
- Revamped UI, title screen (more changes to come, I'm still not happy with it)
- Fixed a typo in Navi's bio
- Fixed a typo in Eka's bio
- Fixed a typo in Mandy's bio
- Fixed Navi's card art (missing bindi)
- Fixed Seraphina's card art (wonky hand)
- Fixed an issue where ToxicCupcake's CGs didn't appear when her card was captured
- Fixed an issue where Charlette's defeat CG didn't appear if white won the match
- Fixed an issue where capturing three cards at once caused CG to appear out of bounds
- Senator's spawn rate in AI decks adjusted

It feels like there’s just too little of everything. You play a match, win or lose, and then get to try again. You can build your own deck, win or lose a match, and then start right back at the…
