We already released a first small hotfix for Elemental War today. It just fixes a bug that could cause tutorial 2 to stuck when upgrading your first tower.
Thanks for reporting this bug to us.

The forums have the advantage that we can directly reply and others see your suggestions, too.

Our usual updates will be released every two weeks on Friday. So the first update will be released on November 2.
