First fo all: The new trap is
much better!
"The Machine": Very clever level. One minor complaint: Currently it is not obvious that gliders starting from the top platform will not reach the button on the other side, but hit the platform below and turn around.
"Harkonnen Force": The timing for the first two climbers who walk into the teleporters requires too much precision, because they must not be too far away (so that they use different teleporters), but cannot be too close together (otherwise the digger will be too fast). And the left third of the level isn't really used at all, apart from making the lemming walk a lot more at the beginning.
