×Flooded Tangle
1S: used Halph to block seep for a while
1S 1W: Used halph to block roach, then used roach to activate pressure plate
2S 1W: Used halph to step on all pressure plates but middle one. Thanks for adding more checkpoints.
2S: Used halph to open all doors. Stepped on all three arrow tokens in process.
1S 1E: used halph to get roaches on pressure plates. thanks for more checkpoints.

Entrance: trivial topscore for first to get in this room? Mind moving conquer token closer to halph so he'll be able to activate it in 1 turn?
1S: used NE stalwart(just killed SW one with slayer - not sure why you included two stalwarts) to turn slayer to the north so he could help me with killing roach
1S 1W: Used slayer to kill eye, both skippers, then used snake to lure him on pressure plate. Please add checkpoints in snake part. Also, conquer token kills optimizing potential for this room(all players have to do is to reach it as soon as possible, and its not too hard)
2S 1W: Used slayer to hold one pressure plates, used mirrors to hold other ones.

Derelict Outstation

1S 2E: Can get goblin in lots-of-pressure-plates-which-should-not-be-pressed area through 25,26 instead of 23,19. Other than that, fine room with well-placed checkpoints
1N 2E: checkpoints please! Other than that, fine platform puzzle
1N 1E: not sure I did this intended way. My solution was like this:

Oh, and checkpoints please!
1E: Checkpoints please! Other than that, fine room. Killed golem at 26,7, used eye to hold both pressure plates.
1S 1E: checkpoints please, this room in particular needs them, because getting serpent at 20,26 is tough(had to use golem to assist me in doing it).
2S 1E: quick and fun efficiency puzzle. Had no moves to spare. Needs checkpoint or two.

Haven Oasis
(second part)

2S: backtracking issue. If I go south before completing it I won't be able to go back and do it. Also, I've got no idea how its possible - by the time I arrive near tar mother its too late. Then again I haven't tried it hard enough(due to backtracking issue). Needs checkpoints anyway.
2S 1E: Used mimic to get roach at 13,13. checkpoints please
3S: not sure I did it the intended way. See attached demo.
4S: used halph to help me get through aumtlichs beam, lured roach on north-pointing force arrow, used aumtlich to break orb, lured eye on hot tiles, used decoys to kill autmlich and roach(second disarm token not needed btw - decoys are placed with swords anyway). Quite fun room. but needs checkpoints.
3S 1W: Seems quite complicated, so I'll wait until you add checkpoints here before playing it
