Yeah sorry about level 12, definitely my least favorite and needed a lot of tweaking. My "design concept" for the blue ladder is that you can stand on top of it and there's just enough time to do so before it rises up, bringing you right to end. If you don't reach power level 3, you can still beat the level but you have to do extra climbing. Looking back that wasn't obvious I'm afraid. Glad you liked it overall though, thanks for playing!
