Cursor Hackathon - Hand Gesture Tower Defense

Last night, we imagined a world without keyboards or mice…

and tied for 1st place at the Cursor Hackathon at the HOUSE 831.

When I sat down with my teammates Geeneth Kulatunge and Jacob (couldn’t have asked for better builders), we agreed on one thing: Let’s build something FUN and COOL. So we built hand-gesture controls for a tower defense game in 1 hour.

What changed the game wasn’t just the speed of vibe coding, but how we approached it. We mapped the architecture first and delegated structured research to Claude. Used Cursor to execute cleanly and quickly. Finally made decisions quickly to implement the new features without prompt spamming or numerous code iterations.

And when it ran on the first try… we were literally jumping.

Huge thanks to Nick R. for letting us build on top of his existing game, also built with Cursor. Contributing to something playable and then actually playing it was unreal. Grateful for mentorship and support from Cal L. and Simon Loewen throughout the event. Thank Jia Ming Huang for organizing this and creating this community in Calgary.

The bigger takeaway? The future of building is about understanding the “why” and “what” rather than the “how”, because AI handles it for you. And honestly? It feels FUN because you can dream anything and bring it to life.
