Gain Factory Reloaded

Gain Factory Reloaded is kittykiller kuriosity's ambitious sandbox factory-builder centered on a fetish premise: construct an automated food production facility to feed a goddess and witness her weight gain progression. The core loop borrows heavily from games like Factorio and Infinifactory, requiring you to mine 15 distinct resources—eight crops, four ore types, milk from cowgirls, honey from bees, and jelly from queen bees—then route them through interconnected machines to create processed foods and factory components.

The pixel-art construction system operates without a grid constraint, letting you place structures at granular precision and interact with machines and characters anywhere on screen. Resource veins, cowgirls, and bees spawn procedurally with variation, meaning each playthrough introduces unique characters to feed and develop. You can undress characters to unlock new clothing for your own customizable protagonist, who can also gain weight alongside the NPCs. The recipe book and in-game goddess dialogue provide onboarding help, though the developer acknowledges the systems can feel "janky and fiddly" during the learning curve.

Progression unlocks three difficulty tiers: the base goddess, a hard-mode second goddess, and bee-focused hard mode. Adult content is woven throughout—intimate moments with characters are available, and the weight-gain transformation sequences are central to the game's appeal—but presented with restraint rather than explicit detail. The pixel aesthetic keeps the tone playful rather than graphic.

Note that active development has slowed, so expect the rough edges the creator mentions. The game is Windows-only and requires patience to master its automation puzzles. For players willing to engage with the fetish premise and tolerate some mechanical jank, Gain Factory Reloaded offers dozens of hours of sandbox building tied to a niche but committed community.
