  • Gameplay
addedThe full version is currently planned to include 144 levels . As you progress through each world, new tools are introduced, allowing you to take on increasingly complex number transformations using concepts such as set difference, greatest common divisors, and removing duplicate prime factors.
addedAfter releasing the demo during Steam Next Fest, I have been making final adjustments for the full version based on play data and player feedback. The current focus includes adding switch and gate mechanics, adjusting the difficulty of individual levels, and improving the overall quality of each puzzle. In particular, for the more difficult levels, I am working to make sure they are not simply about using more tools, but can be solved through careful observation and insight.
changedThe launch is getting close. I will continue making the final adjustments toward release.
