Senior Software Engineer · Creator of Chalo Jantar Mantar
I'm Sandeep Sahu, a Senior Software Engineer from India. I designed and built Chalo Jantar Mantar on my own: a free 3D online multiplayer satire game you can play in the browser at mantarjantar.in, or as an Android app.
🎮 The game
- Chalo Jantar Mantar is a light-hearted 3D street game about the road to Jantar Mantar, New Delhi: lead a kafila past the barricades as ✊ andolankari, or hold the line as 👮 Dilli Police.
- Online matches of up to 15 vs 15 real players, with bots filling the empty seats, and offline practice.
- 3D characters you can dress up (kurta, saree, salwar, safa, gamchha), crowds of hundreds, festivals and daily challenges.
- Free, no sign-up, on PC, mobile and Android. Launched in October 2026.
🛠️ How it's made
- Written in TypeScript; the city and its crowds are drawn with three.js (WebGL), hundreds of people animated on the GPU.
- Real-time multiplayer with Colyseus; the same game rules run on the server and offline in the browser.
- Design, code, art direction and the server: a one-person project.
- 3D models from Quaternius and Kenney (CC0, public domain).
