Missions and challenges have been completed in full on all difficulties, all costumes, weapons and inventory are open. Used a trainer during the passage.
The main feature here is that vibration is disabled in the options. The fact is that all the saves that I could find were made with vibration enabled, but after all the patches, including patch 1.09, a bug remained in the game: when you try to disable vibration, the game crashes; this also happens if you play with vibration (as soon as the enemy hits the heroine, the game crashes).

In patches 1.07 and 1.09 (possibly in the early ones, I don’t know), vibration is disabled by default, and you can play the game, but saves with vibration enabled are still useless. For this reason, I made and posted this save. Perhaps someone who also encountered such a problem will find it useful.
Throw the savedata folder from the archive into the game folder. Saves are made on a repack from Codex.
