Any help for the stars in 14,17; 11,12; 14,19; 11,18; 7,21? (I need 2 more stars for the door.)
While I've already unlocked the cryptid door there's obviously more out there; I assume I'll need to double tp in these rooms and have no clue how: 7,16; 6,18 (...well, I have some ideas, but the execution looks like it'll be hell); 18,17 (apparently you can't do this the obvious way to bring two in from below because of the differing amounts of ice); 13,8
Definite spoilers below:
For 14,17 push a dead cat down from above.
There is a discussion of 11,12 at https://itch.io/post/7161525 .
For 14,19 rocks collide with flags and stars, so push the star out.
For 11,18 push a dead cat down.
For 7,21 use the rocket/finale mechanic to your advantage. and push a dead cat up.
For 7,16 cryptid push a flag with a rock to revive the second cat.
For 6,18 I assume you already have the room above? If you do, make a loop at the bottom right by pushing the rock down. You'll also need a dead cat on a wormhole.
For 13,8 the game always takes the higher number of steps, so you can save on a 0-flag without dying.
I hope this is enough :)
Definitely helps.
11,12 is still hard. The reason I had no ideas is because I forgot about how execution order works, so I wasn't even sure how to get to the other side. Once I got that part it just got to the fact that this puzzle is kind of difficult.
11,18 That was the obvious part. I ended up messing around until I somehow managed to have two alive cats in different columns, after which it was easy.
7,21 I did try going to the upward transition above the 0 flag to see if it'd help, but didn't see any way it'd be possible to actually get there.
6,18 I always forget about dead cats. That makes this pretty easy.
13,8 The specific part I'm struggling on is that part with the three flags and three rocks that makes a wall that you can't pass. The obvious solution would be to run forwards through the room first, but then there's an obstacle after that point that you can't pass without a zero flag, and at that point you haven't revived the second cat yet.
(also the 18,17 in the original post was a typo, meant 8)
For 8,17 you do come in the way you think is obvious. You are right that you need the same amount of ice between the cats and the exits. That level contains everything you need to make that happen (except for one spare cat you'll have to bring with you - I don't think you have enough range of motion otherwise, at least I never found a way without it).
For 13,8, you're actually on the right track when you realized that you can't get past the wall. If you push the only rock you can push, it blocks the hallway. But you do have to get on the other side of the rock. So if you can't pass the rock, the rock has to pass you. You're going to spend a lot of time carefully moving the revived cat around. MetaMetaPuzzle gave you the key here, although to restate - a 0-flag doesn't have to kill you.
In 7,21, to restate again, a 0-flag doesn't have to kill you. As discussed somewhere below, there is no way to send two cats to the left side and then revive them, so you'll have to use "something else" to push a dead cat.
You can also get to 11,12 by double-teleporting. It won't help with the star, but it gets a cryptid.
