Mature Content Description

The developers describe the content like this:

MATURE CONTENT DESCRIPTION

Sexual content:
- This game contains explicit, adult-only sexual content, including nudity with visible genitalia.
- Explicit content appears in: pre-rendered "liberation" cutscene videos shown after freeing defeated guardians, unlockable collectible cards and "photo" images, and the in-game gallery where unlocked scenes can be re-watched. All of this content is pre-made and ships with the game; none of it is generated at runtime.
- Dialogue throughout the game contains frequent sexual themes, innuendo and crude sexual humor, including references to pornography, adult games and masturbation.
- One scene implies a female character masturbating (silhouette and sound; brief).
- All characters are adults.

Consent framing (topics players may be sensitive to):
- Enemy guardians are adult female fantasy creatures. The player defeats them in combat, after which an optional "liberation" scene plays. Within the story these scenes are consensual and merciful — the characters are suffering spirits who thank the player and welcome their release in on-screen dialogue — but because they follow a combat defeat, players sensitive to dubious-consent framing should be aware of this structure.
- One optional scene involves voyeurism: the player briefly observes a ghost in an implied private moment; she notices the player, smiles, and vanishes.
- The game contains no depiction of sexual assault or rape.

Violence:
- Mild cartoon first-person shooter violence against fantasy creatures. No blood, no gore, no dismemberment.

Language:
- Moderate to frequent strong language in dialogue.

Sensitive story themes:
- The protagonist is hit by a car (brief, non-graphic) and the story takes place inside his comatose mind; themes of coma and death are recurring.
- In one ending the protagonist can choose not to wake up from the coma, which narratively leads to his death (no suicide or self-harm is depicted).

About This Game

You spent your life playing lewd games. Then a car hit you — and now you're in a coma, trapped in a dungeon built from every naughty fantasy you ever had. Congratulations: they all remember you.

Portal Deep is a fast-paced retro FPS about descending through the 12 floors of your own dirty mind. At the bottom sleeps the Source that can wake you up. Between you and it — the girls.

THE GIRLS

• Elira — the silver-haired keeper of your mind. Curvy, cruel, and the only one honest enough to call you a pervert to your face
• Lyra — the pink-haired gunsmith. Run errands for her and she might let you see her «private collection»
• Nova — the brainy one. Upgrades your half-dead body for memory sparks. She swears it doesn't hurt. She's lying
• Sable — the swimmer girl who surrenders instantly and moves in by your pool. Losing her best-swimmer medal was maybe not an accident
• Rhea — florist, poetess, and your actual ex. She only says what you want to hear. That's the problem
• ...and the guardians of every floor: sirens, bone dancers, rose witches, wraiths who moan in the dark, and a seraph in lingerie armor who calls you unworthy. Prove her wrong

BEAT THEM. THEN «FREE» THEM

Every guardian can be defeated — but killing is for cowards. Get close and release them instead: each liberation is an intimate, artistic little scene, and every girl you free is one less demon in your head... and one more photo in your collection.

GO FAST, SINNER

Bunnyhop, air-strafe and surf like it's 1999. Speed carries through portals, orange gates skip half a floor if you're fast enough, and a dedicated speedrun mode cuts every story stop. Yes, you can speedrun through your own repressed feelings.

YOUR REWARDS

• Spicy collectible cards — cut the packs open yourself
• A phone full of «photos» that warm the soul. And not only the soul
• A gallery to revisit everything you've unlocked. For research
• An in-game MP3 player — drop in your own tracks and bhop to them

THE DEEPER YOU GO, THE MORE HONEST IT GETS

A nurse who reads your phone while you sleep. An orgasm journal you really shouldn't open. A shadow wearing a familiar face. Two endings, one secret one — and the question the whole dungeon keeps asking: is waking up even worth it?

Full interface and subtitles in 7 languages. No actual nudity — your imagination does the heavy lifting. It always has.

AI Generated Content Disclosure

Parts of this game's content were created with generative AI tools: character and enemy artwork, adult cutscene images and videos, collectible card images, some textures and parts of the soundtrack. All AI content was created during development and ships with the game — nothing is generated while you play. The story, level design and code are human-made.
