I immediately noticed that the map is “terrible” because it is designed not for ordinary people, but for heroes of labor (who waste precious time and nerves on replaying) or console heroes (whom I sincerely do not understand). It is very reminiscent of the works of a misanthropic nature by a well-known and, unfortunately, already retired master. That is, you play it and forget it, like a bad dream.
The message that appears before the window was about the fact that the ring allegedly was added to the player's inventory. But it should not be added (because the enemy with it is reusable). This is a feature that I implemented due to the specifics of the game mechanics. There is a note about this in the v0.1 section of the "Change Log".
