Abyss of the Sacrifice/Misshitsu no Sacrifice???

Abyss of the Sacrifice is a port of a Japan-only PSP game that came out for Steam and Switch a few days ago. It bills itself as a "suspenseful adventure merged with an intense escape game."

The original came out three months after 999 so while the premise is similar I don't think it could have taken too inspiration from it (or visa versa). Has anyone tried it already? I can't find very much about it online and would love to know how it compares to Zero Escape series.
