Major Update: Version 3.0 with Free DLC

Hi Everyone!

So thrilled and grateful for the positive feedback we've been getting on the game - we never expected it would gain such a following. We've been working around the clock to add tons of new features asked for by the community and lots of stability improvements, all outlined below!

  • Free DLC section added with levels by famous mathematicians like James Tanton and James Grime!
  • Tons of changes under the hood for vastly improved performance and responsiveness, - bottom to top refactoring plus lots and lots of bug fixes
  • Ability to create and play community levels without beating the game.
  • Community level system completely overhauled, now runs on Math.js:: this means levels can be far more sophisticated (i.e. complex numbers) with less programming and more intuitive syntax. Also far more stable and safer.
  • Ability to copy formula history to the clipboard (by popular demand ːsteamhappyː)
  • More seamless Wolfram alpha integration
  • More intuitive menu design
  • Lots of other subtle improvements and optimizations.
  • Better help resources, including a new User Guide

I still feel such a moron about the two hour downtime on launch day ːsteamfacepalmː (since isolated so it can never happen again). Really excited to share this new version with all of you and I appreciate your support and interest more than you realize.

Please contact me with any issues or questions at [email protected]
