Thin Walls

18+ · Romance Visual Novel · PT-BR / EN · PC & Android

2:40 a.m. Rain on the glass. Through the thin wall of apartment 7B, someone starts playing the piano — beautiful, sad, and always stopping on the exact same note.

The story

Nina, 26, is a freelance illustrator who just moved into an old building in Curitiba, three deadlines late. Theo, 28, is the bartender next door — a former piano prodigy who froze at a competition final four years ago and has never finished his song in front of anyone since.

It starts with knocks on the wall and notes slipped under the door. Then a jazz bar called the Blue Hour, an umbrella too small for two, a Halloween party on the rooftop, a blackout lit only by candles… and an offer from Lisbon that could put an ocean between them.

Features

• 6 chapters with dual point of view — you play both sides of the wall
• Choices that shape bond, honesty and art — every drawing Nina makes counts
• 4 endings: One Wall Less (true), Letters from Lisbon, Silence in 7B and a secret ending
• A generative piano theme that stops where Theo stops — and only plays in full when he does
• Fully bilingual: English / Português (BR), switchable anytime
• Auto, Skip, Log, 5 save slots + autosave, endings gallery
• Single HTML file — plays offline on PC, Mac, Linux and Android
