About The Gain Trials
The Gain Trials is a Ren'Py kinetic novel by Bladerune9 with 3D rendered visuals. You play as a male head scientist running experiments on three women, Tracy, Sarah, and Krystal, whose bodies change and milk production increases as the trials progress. The game focuses on transformation and lactation themes, with simple story-driven play and occasional interactive segments.
Development is ongoing. The May 13, 2024 build is v1.6.1, available for Windows, Mac, Linux, and Android in English, uncensored. This update adds six early stages for Tracy and Krystal, plus seven for Sarah, rewrites most dialogue, introduces a mixing minigame, brings two characters with limited interactions, and provides extra visuals and animated sequences. The project began with the earlier v1.1 initial public release.
