The game will be 3d models standing in for 2d sprites, allowing for flexibiltiy in animation and clothing. Starfire will have destructible clothing that gets worn down fighting, which can be repaired or replaced in game.

The station uses a “credit system” to incentivize the girls, who can obtain store credit from having sex with the customers. In theory with enough credits they can purchase their contract and leave, but in practice the company store system with it’s abusive prices ensures this will never happen.

Starfire is not interested in this game but wearing the collar means she is part of the credit system. Every time a customer has sex with her she will receive credit, which can be used to purchase healing items or repair/buy new clothing.

Clothing system

Starfire doesn’t really care about being naked, but the station uses a clothing related pricing system meaning the customers pay based on outfit rankings. A naked girl is cheapest of all, while various tiers of outfits increase her price. Since credit is deducted automatically in gameplay terms this means wearing some outfits will make customers avoid Starfire altogether, and bring in more credit when they don’t.

Other slavegirls may try to steal expensive outfits.

Certain outfits may be necessary to access specific areas.

The slave collar

In game, Starfire is wearing a collar that restricts her powers. The slavers did not anticipate the energy release when she climaxes so the collar is damaged, they can no longer track her and the power damping is offline until the collar reboots after a cooldown period.

With powers Starfire can fly, fire starbolts and punch and toss her enemies around with ease. When the collar reactivates she can only walk or run and grappling/punching becomes a lot harder. (She retains her resistance to damage because having girls that can take a beating is considered a plus). Even fully powered Starfire isn’t strong enough to rip off the collar, getting it off or permanently disabling it is her number one goal

In game you can resist a grapple physically using the left & right buttons rapidly to break free. If Starfire cannot break free or does not resist many npcs will initiate sex, at which point you can use the up & down keys to control the arousal bar

Arousal mechanic

There is an arousal bar that will fill up gradually as Starfire becomes aroused by sex, groping or other circumstances such as masturbation or items. But! Not every orgasm will produce a jolt big enough to disable the collar. If her orgasm is low quality she will not produce enough energy, the arousal bar will be reset and the power damper will be unffected. Damp squib orgasms can be caused by masturbation (To avoid players having an easy way to recover powers) , being fucked by crappy tiny dicked customers, or by not being in the orgasm zone long enough.

This is why the orgasm resistance keys need to be pressed, to retard Starfire’s orgasm to prevent wasting accumulated arousal and to make sure it’s a “big one”.

Example scenario: A robot guard is approaching, Starfire allows herself to be mounted by a little green alien who begins pumping away at her doggie style. Security robots are programmed to not disturb customers so he serves as cover.  Rapidly pressing up & down the player prevents Starfire from reaching climax and wasting an orgasm until the robot rumbles by and, pressing right & left Star rapidly shakes him off and tosses him aside.

There are three kinds of npcs in the game, guards, customers and slave girls.

Guards are either heavily armed alien mercenaries or robots, they will attempt to hunt down Starfire and capture or kill her. Fully powered Star can hold her own against them, but wthout her powers she must flee and hide. Guards are programmed and instructed to avoid bothering customers.

Customers are a variety of horny aliens interested in having a good time, they will attempt to fuck everything they see, because that’s the whole point of this place!  They can be used as cover to avoid the security searches but they will try to fuck Starfire, and if she needs her powers to get past an obstacle she’ll have to let them.

Slave girls are fellow victims of the alien slavers, they will be found wandering about the play area having sex with clients and along the background and foreground being fucked (See the same effect in Parasite in the City). They will belong to various alien races (Potential scope for cameos). Some may be hostile or delay the player or provide information.

Blackfire has engineered this situation to pay back her gambling debts, but once she finds out her payment has escaped she is in trouble with the station owner who threatens to take her instead.

Blackfire will use a communicator to contact Starfire, who doesn’t realize her sister set her up. Pretending to guide her, Blackfire will actually lead her into ambushes and try to get her captured. Starfire still thinks she is “rescuing” her sister.

Potentially, Blackfire may be a playable character for a stage when the boss gets tired of her and tries to have her captured.

The big bad boss: Some generic Jabba the Hutt type? Suggestions welcome.

Plot

Blackfire is kidnapped by aliens on Tamaran, Starfire goes to rescue her but is brought down by… Blackfire who was really in league with the aliens. She is sold to a giant asteroid space station/whorehouse she must escape from…

Gameplay

Side scroller with RoR elements. In my previous project a common objection to the RoR game style is that “you get rewarded for failing”. While I don’t quite agree I came up with a mechanic to incentivize getting caught by enemies strategically, the inhibitor collar mechanic.

Power loss mechanic

Starfire is captured and fitted with a power draining slave collar at the start of the game.  However as she begins to be trained as a sex slave, her first orgasm releases a powerful surge of energy that overloads the collar. She recovers her powers, blasts her captors and escapes into the station.

As she flies around looking for an exit the collar resets and she falls from the sky, powerless. The collar is damaged but she cannot remove it and the only way to temporarily disable it is via an orgasmic power surge. She must now evade the station guards who want to recapture her by blending in with the population of the asteroid.
