release a version for geometry or trigonometry, or open up an API for customization
I find that this approach for algebra really speaks to my kids, much more than manipulatives. As I have gone through it with them, I found myself thinking that I'd love to see this for geometry and/or trigonometry or even math logic, like complex boolean algebra expressions. Your platform is genius. Have you ever considered opening up some as an API for people to add their own problems to?
I can't wait!
A new game is in the making, and it will indeed be about geometry! Keep an eye on our Facebook/Twitter for updates.
We need to finish the new game first, but afterwards we will look into customisation features for DragonBox.
