Updated February 20th: we’ll release the new Arena next February 27th. The reason is finishing the manual, testing some new features we thought were important to add right now, and make final tests to the whole game. Sorry for the delay.
We’re working hard to improve the new free Arena of Math Combat Challenge, whose final name will be “Pyramid”. In order to finish it the best way we’ll release the new version next Tuesday 27th. Thank you very much for your support.
