Sixth yearly edition of the online competition for web game developers just started! Join Gamedev.js Jam 2025 on Itch – you have exactly 13 days between April 13th, 5 PM CET and April 26th, 5 PM CET to build an HTML5 game and win cool prizes in the process!
Theme
This year’s theme is… BALANCE!
As always you are free to interpret it however you like. Balance can mean physical equilibrium on a scale, or stability during sports. It could be you bank account’s balance, or mental steadiness. Your entry can focus on physical balancing, resource management, combat balance, moral or life balance, symmetry and aesthetics, ecological balance, or even controlling two things at once.
Balance is a versatile theme and can inspire a wide range of creative interpretations!
