Spoilers ahead for an 8-year-old game, but the journey is worth experiencing blind.
Act 1: The Temptation’s Gate (Forest Exterior) The game opens with the protagonist fleeing a storm. The castle appears inviting—torches lit, gate open. A ghostly female figure (the Queen's projection) greets you: "Tired, little wanderer? Rest here. I have warm beds. I have soft arms." The first puzzle: a sign that says "Turn Back," but the path behind you crumbles. You must enter.

This means you cannot simply "collect all the loss scenes" in one playthrough. You must actively resist to see the true ending.
Little is known about "Poring." The username is a direct nod to the iconic slime monsters from Ragnarok Online, suggesting a deep roots in early 2000s JRPG and online gaming culture. Poring developed the game using Adobe Flash (later ported to standalone .exe for v1.0) over the course of roughly four years.
The v1.0 release, dated around 2016-2017, marked the developer’s departure from the project. Poring released a final statement with the patch notes (excerpt below):
"This is it. The full circle. Castle of Temptation is now what I envisioned. No more episodes. No more act breaks. From the forest gate to the throne room, the story is complete. Thank you for falling. – Poring"
