Quote:The way it's set up now, the second red key is redundant. Perhaps add a blue key or chip behind the other red lock?
Please illustrate with a video why the second red key is redundant. As far as I can tell, the first red key, at (27, 1), has to be used on (20, 7). If it's used to get the blue key, you won't be able to get the exit because you still need all of the chips. Are you mistaking the block cloner on (17, 12) for a block that can be pushed north to get to the exit?
It might be more elegant to replace the blue key and blue lock with a chip and a chip socket, though, now that you bring this up.
