Libido Space is a pixelated action game by Dai that uses the Others engine and a 2D animated style. You play a female protagonist given a rescue mission in a certain universe, entering a spaceship alone to help its inhabitants while fighting monsters. The design combines platformer-style action with adult fantasy, sci-fi, and monster girl themes.
The current build is the v4.93 demo, released July 19, 2026. It runs on Windows in English and Japanese without censorship. The latest available changelog is for v4.82. That update fixed a problem where several character portraits and lines of text appeared together, corrected the camera issue that followed, and added objects that explain the game during play. These objects cover the favorability system at the item shop and provide a pre-boss explanation plus autosave after the event before Stage 1's boss.
Developer's description
This is a pixelated action game set in a certain universe, in which the protagonist is given a rescue mission and enters a spaceship alone, rescuing the inhabitants and battling monsters.
v4.82
◆Fixed an issue where multiple character portraits and text were displayed at once.
◆Fixed a camera issue that occurred as a result of this.
◆Added an object to explain the game during gameplay.
Locations
1. Item Shop (Explanation of the favorability system)
2. After the event before the boss in Stage 1 (an explanation that this is before the boss battle and an autosave)
That's all for the updates!
[Notice]
2. When the trial version is updated to a new version, we've confirmed that starting from saved data can cause bugs due to program differences with the previous version. In this case, starting the game from the beginning seems to work without any issues. (If that happens, it will be a pain to start over, so perhaps it would be better to just place the stage unlocking object in the trial version...?)

◆Fixed a bug that caused the uterus birth animation to start after a certain amount of time when eggs were laid in the anus.
◆Attempting to fix a bug that caused game overs due to inability to control characters when restrained by breast-expanding tentacles.
*Fixed a bug that caused the image of the bloated belly displayed when eggs are laid in the uterus and parasites are placed on the breasts to be incorrect.
◆Changed the feature that caused the player character to disappear when their health reached 0 after being restrained by a monster, so that the player character does not disappear and an erotic animation starts.

PROS: Though there's a limited amount of enemies (playing v4.93), what is there shows some promise. Combat is basic, but solid enough. Developing relationships with NPCs should be an interesting mechanic when implemented. CONS: Wall jumping mechanic is frustrating, and…

This game is still in its early-mid stages, but it is genuinely a masterpiece (for this genre). Incredibly good depictions/art of the protagonist's over-expanded chest, and her pregnant belly. This game plays a lot like CelSector , if it was…

Played 4.82. It is an alien/tentacle hentai 2D sidescroller. The CGs, artworks and animations are great, like the portrait art, status screen, the npc event, etc. However the gameplay is low resolution pixelart. I like the body modification pregnancy gimmick…
