So I've adored this series (primarily because I've played the two previous games through CoolMathGames on an iPad) but I've gotten stuck on 3. I can't activate the switch. Is it that it's not ready for iPads/Mobile yet, or is it a bug?
Sorry for taking this long to answer ! And sorry again for this bug, I hope it didn't ruin your overall experience!
Maybe this is a bug, I test it on mobile some times =/ That said, the Coolmath version is fully tested and works fine on mobile, so I would recommend you try it :)
