Product summary

Lock disengaged. The heavy cell door opens into the silence.
The facility has fallen, now transformed into a labyrinth where desire and malice swirl.
A world of madness where the boundaries of flesh are violated and rewritten.
The pitiful souls left behind must resist -- either surviving the aberrations prowling the darkness or having their bodies claimed by them.

"CelSector"
An sci-fi side-scrolling action shooter featuring exploration across a vast map.

High Volume Content

* Over 35 types of enemy sexual animations via Spine
Infected zombies, mutant insects, tentacles, parasites, aliens, and more -- over 35 unique enemy types appear. Every enemy features fluid, multi-stage sexual animations implemented using Spine 2D.

* 6 stages of meticulous hand-drawn art
Prisons, corridors, sewers, insect nests, laboratories, and the interior of a parasite... The background art, drawn in extreme detail, invites you into a bizarre world.

* Outfit unlocks and character customization
Acquire equipment during exploration to freely customize the character. A wealth of outfits is available, including bikinis, mini-skirts, swimsuits, and knee-high socks.

Sexual Systems

High-definition sexual animations
Enemies will attack to capture the player and prey upon their body.
If resistance from the restraint (button mashing/rapid inputs) fails, the sexual animation begins.
Every enemy has unique animations, featuring progressive sequences from foreplay to penetration and climax.
Insemination, Pregnancy, and Birth
Certain enemies will plant seeds within your womb (insemination), forcing pregnancy.
As the pregnancy progresses and reaches full term, the player will collapse on the spot and give birth to the type of creature that fertilized them.
After birth, the body enters a lactation state, and due to this physiological phenomenon, the breasts are forcibly enlarged.
The player will be humiliated as a seedbed for these aberrations, with a swollen stomach and chest.
* All of these physical changes are fully compatible with the sexual animations.
Status Ailments (Bad Status)
Many enemies and environmental traps cause various status ailments that affect gameplay.

* Abdominal Semen Retention (Creampie Belly) - The stomach swells with injected semen, slowing movement until it subsides over time.
* Lactation Constitution - Breasts become tight and expand greatly due to milk secretion.
* Trance - Consciousness becomes hazy, making it harder to escape enemy restraints.
* Mucus (Slime) - The entire body is covered in sticky fluid, reducing movement speed.
* Aphrodisiac - Sensitivity increases due to the drug's effect, making all stimulation easily turn into pleasure.
* Spider Silk - Sticky threads tangle around the body, restricting movement and making walking difficult.

...and many more!
Outfit Destruction (Armor Break)
When caught by an enemy, the worn clothing sustains damage.
Each part has up to 3 stages of damage states (variations), each with dedicated art.
Tears and rips are reflected dynamically and maintained during all animations.
As clothing is destroyed and skin exposure increases, it becomes more difficult to shake off enemies and escape.

Color & Texture Modification
Each part can be changed from a color palette of up to 40 colors. Additionally, up to 4 types of texture variations (patterns) can be selected.
Skin color, hair color, eye color, and more can be adjusted in detail to suit your preference.
Many garments have shape variations, allowing for highly specific styling.
For example, socks can be changed to ankle length, knee-high, or thigh-high.
For tank tops, you can select standard length, cropped length, or provocative styles that show the "southern hemisphere" (underboob).
Outfit Saving
To further enjoy dressing up, you can save up to 3 coordinate presets.
These can be switched instantly within the gallery (recollections) or during gameplay.
