Decaying Numbers is a 2D puzzle platformer where you play around with "countdown blocks". As their countdown hits 0, strange things will happen... Use their effects to solve increasingly harder puzzles that will melt your brain, with some platforming.

Made for GMTK Game Jam 2026. My first game!

Since I've had so much fun making this during the game jam (I ran out of time), a more complete version will come out later with progress saving, settings, controller support and support for other platforms. Oh, and with many, many more levels, of course, all for the price of [free].
