I recently took part in **GMTK Game Jam 2026**, where the theme was **Countdown**.
For the jam, I decided to make a tower defence game called **Countdown Tower Defence** โ and this video brings together footage I recorded throughout the entire development process.
Rather than being a traditional tutorial, this is a **game jam development vlog**, showing the different stages of making the game, the ideas I had, the development process, and how everything came together under the pressure of a game jam.
๐ฎ The Game:

The goal was to take the Countdown theme and turn it into a tower defence game, building the concept and mechanics from the ground up within the game jam timeframe.

โ The Countdown theme
โ Coming up with the game idea
โ Building Countdown Tower Defence
โ Developing the core gameplay
โ Game jam development footage
โ Problems and challenges along the way
โ Putting the final game together
โ The finished result
This video is made from several clips I recorded throughout the jam, edited together to show the development journey from start to finish.
If you enjoy **game jams, game development, Unreal Engine, tower defence games, and devlogs**, hopefully you enjoy watching the project come together!
