Hello everyone and welcome to Math Classroom Challenge.
We have moved the release date to June 7, because we are working on some final elements with the Oculus version of the game, and we want to be sure everything is working as expected.
Meanwhile we are also adding some new features that were implemented in the AR version of the game, so you'll have a better final build at the day of the release.
Thank you and sorry for the delay, have a nice math day!
