Kreygasm

so i got this got all sigils and stars A world all sigils B world, have no idea how to get B4 sphinx star, B5 obelisk star and B7 pyramid star 24/27 sigils and 7/10 stars C world (didnt get C1 "multiply impossible ascension", C4 "oubliette", "throne room" sigils and C4 "oubliette", C5 "dumbwaiter", "up close and jammed" stars) i dont know how to get C star sigils. A star and B star are ez but i have no stars to unlock A star i need your help guys to finish it :)

i dont know how exactly it works, it was useful for me once when it dropped me right into sunshot sigil. if it was stable it would be possible to do whole b3 from eagles nest

i was practicing b3 fan slides and found something interesting :) never saw it b4 (damn i hate this cube stucking so much) btw hello everyone im new here :D
