Well thanks for the feedback on my lack of feedback (:
That's the kind of stuff which is more effective on paper than ingame. This level 5 was truly a mess to put together. There's some written hint however: level 5 is a 3-part level and you can see where you are at the upperleft.
Maybe it's not that obvious but i also tried to play with player memory. The switches are slightly different (maybe they should be more?) to correspond with the action they initiate. There could be letters or numbers to indicate what do they do where i guess... But too much info wouldn't help the fun.
All in all i appreciate the confusion it brings at final level... But i do understand your comments.
Thank you for this constructive review!
