Reduced a star for two reasons: 1. Rotating that thing was really annoying, the R bots fall down most of the times. 2. To pass that maze, we had to rotate the fan and the metal pillar was needed to complete the path but whenever Pillar R stepped on it, it started wobbling and fell down the level two three times. Restarting was again annoying. But still the idea was great. If you could do something for these instabilities, I will definitely rate it 5
I agree with @ADM , though I can see the instability as ability challenge. The level would have been a bit trivial if you could just set the wheel at any 90 degree angle for each passage.
I agree with @Block builder that the level would have been too easy with a smooth turning wheel. Mind you that wasn’t what i felt when B fell through the 2nd last gap with the other two bots in place!
I will follow @Block builder reasoning and rate with five stars, although I suffered the mechanism a lot. Thanks!
