Five Nights at Fionna's

Five Nights at Fionna's is PrimaryStrawberry's irreverent take on the FNAF formula, replacing jump-scares with body modification mechanics and adult humor. You play as a night guard monitoring Fionna through a tablet interface, using an inflation app to strategically expand her assets as a defense mechanism against threats. The premise is deliberately absurd—survival depends on your ability to manipulate her proportions to slow her down or prevent her escape during encounters.

Gameplay centers on resource management and timing. You'll balance your inflation app's energy reserves while monitoring Fionna's status, deciding when to deploy modifications to keep her contained or compliant. The five-night structure mirrors the original FNAF, but tension here derives from the fetish mechanics rather than traditional horror. PrimaryStrawberry uses 3D assets built in Blender to render the game world, running on Godot 4.2.1—a choice that gives the project a clean, accessible feel across HTML5, Windows, Linux, and Android platforms. Sessions are short, making this a quick playthrough rather than an investment.

The adult content here is explicit in premise but restrained in execution; the game prioritizes the kink scenario over graphic depiction. If you're familiar with erotic indie VNs, you'll recognize the tone—playful, unapologetic, and self-aware rather than trying to masquerade as something else. Be aware that the developer has noted significant bugs accumulated over time and mentions they may not fix all issues, so expect occasional technical roughness. The original, more stable version (Fionna Manager Decomp) remains available on the developer's itch.io page if you want a more polished experience.
