Viva Project

Interactive anime role-play with reactive AI and standout 3D visuals

Viva Project is a free role-playing experience from Poison Pill that blends life sim mechanics with AI-driven character interaction. You inhabit a richly rendered 3D setting inspired by Mexico, complete with a charming colonial home and a relaxing hot spring, where much of your day-to-day play unfolds through conversation, play, and light activities.

Progress revolves around small, satisfying tasks and dating-style encounters. You start with a single companion, with additional characters unlocking over time. Each one has a distinct look, and how you treat them influences their mood, giving your choices a noticeable impact. The real hook is the way characters respond. Movements and reactions feel grounded in IK-like responses and complex behaviors, so your companion is not just following scripts but actively reacting to your prompts, props, and the environment.

Presentation is a clear strong point. Character models are vibrant, environments are detailed, and animations have the fluidity you would expect from polished anime productions. The hot spring area, in particular, becomes a natural hub for playful interactions, from chatting waist-deep in water to taking a swim together.

The trade-off is stability. Crashes are reported often, with the inventory screen cited as a frequent trigger, and interruptions can also occur unpredictably during regular play. If you are sensitive to technical hiccups, those issues may disrupt the otherwise engaging rhythm.

For fans of anime life sims who value emergent interactions, Viva Project delivers a distinctive sandbox powered by advanced AI behaviors and eye-catching visuals. It asks for patience with its tendency to crash, but when it holds together, the combination of responsive characters, mood-driven relationships, and an inviting setting makes it easy to lose track of time.
