@Tacho Go to the pink Options page in Mekorama and make sure Free Camera is turned On. Most levels here can't be completed without it.
Not a fan of hidden - the red brick was a little much and getting the 2nd ball was hard to tap and for what reason? The mechanism didn't work on my 1st attempt and on the 2nd attempt, it was well over 1 minute before the zappers raised. No idea what R was doing inside so just gave up.
@gmacpro ....what does R do? Spoiler: R R going over the zap and round the back triggers the rise of the winblock independently of the other mechanism. The two balls are needed to raise the zap mechanism.
@ridgerunner - Thanks but I have a hard time winning this creator's levels that I can see so I'll not be wasting any time playing his hidden ones.
