@Tutankhamun - I gave up as the rotor in the corner had square blocks and made too much noise as it hit the fence over and over. If you would have used rounded corners then there wouldn't have been any rubbing and therefore no noise.
@Meko Guy thanks for letting me know about thr noise - I play and create Mekorama levels with my phone on mute - so I wasn"t aware of the noise from the rotators.
@Tutankhamun - I play Mekorama on my PC with my sound card feeding into my house speakers so what I hear on my PC, the whole house hears so noisy levels must be skipped.
Too many Z's and you can win with Z's alone, even though B is already off. Maybe you will see that you can structurally keep the Z away from the stars. Then the level becomes a challenge.
@Meko Guy : Yes, there is a lot of noise in some levels. Also in this, which unfortunately is due to the Mekorama app. But you can switch off FX, then unfortunately you can no longer hear water splashing and reaching a star. I actually always try to avoid the clutter of mechanics, but I don't always succeed. I think @Tutankhamun has to try so that moving parts don't scrape along anywhere.
I don't enjoy the quick start - no time to even look where B is, where the stars are, no way to know you need to move, or where to, you just get zapped, ! Having had the first fail, it's then just a case of getting B quickly to the first star and sitting back to wait for one of the Zs to wander onto the lifts to the other stars. It really needs more active gameplay, and fewer Zs to make a more enjoyable level, .
