⚙️ COGS UP!

Spin the system. Solve the chain. Avoid the lasers.

Cogs Up! was made for the Gamedev.js 2026 Jam, themed around machines. It's a puzzle adventure where your goal is to get all cogs spinning by placing them into a working chain.

- Watch out for lasers.
- Plan your placements carefully.
- Make everything connect.

This is more of a tech demo with incomplete mechanics and levels. I didn’t originally plan to participate, but the gameplay loop turned out surprisingly fun, and I jumped in during the final days.
