Some problems in Keep of the Plains:
I can sequence break on this screen by jumping down from the northern platform and, while in mid air, using the hookshot to reach the tile just above the lowered gray peg.
After the tricks in the room below this screen, I can then hookshot to the blue statue and bypass the light orange peg (and thus the puzzle) completely.
Unfortunately, the blue/orange revolving switches (the proper name of these escapes me) don't work correctly. This is difficult to describe without a video, but the bottom revolving switch (orange in the screencap above), when I step on to it from the south, automatically transports me twice in such a way that I end up on the northern side of the switch. I should end up on the eastern side, but the switch automatically transports me again once I reach that side. The blue switch in the screencap also does the same thing as the bottom revolving switch.
Then, the topmost revolving switch (also orange in the screencap above) isn't working correctly either. The problem with this revolving switch is that, if I try to bypass the pegs with the hookshot and approach the switch from the west, when the switch is in blue mode, the switch automatically turns orange and transports my character back to the north instead of to the south. Effectively, this specific switch problem seems to make the intended solution to these three screens impossible and is the reason I found the sequence breaking in the first place.
I can't finish the Keep of the Plains because there's no way to reach the southeast doorway in the last screenshot in this reply.
