M35 S4C: Pos. 59 is an unhappy Dash Jets 2 choke-point. You can easily go through it leftwards, to head over to the 200-mineral in S3F, but getting back through it rightwards is probably F6-inducing.
Virgo 02: Hidden door could use in-wall tiles.
Virgo 34: The lower-right magnet block remains permanently destroyed, and explodes when you return to the room. Not entirely sure why this is here since it's a short cut to the Stomp Boots, but you can reach them the normal way with the Grabber.
