The demo of Nox Mortalis initially disappointed the player due to its cryptic nature and frustrating melee combat mechanics, including a reliance on a parry system and the absence of a compass. However, after reviewing the in-game manual, the player discovered that crafting a compass was part of the gameplay experience. The game incorporates resource management, requiring players to gather materials like wood, coal, and metals to craft weapons and unlock treasure chests. The crafting system is intuitive, with recipes unlocking automatically as players collect materials. The demo allows for approximately four hours of gameplay, including exploration of side dungeons and the initial levels of a central megadungeon. The player experienced a satisfying progression, starting with basic crafting and advancing to more powerful weapons. There is concern about whether the developer can maintain the engaging gameplay loop in the full release, which currently has no set date, as feedback from the demo is being gathered. Players can wishlist the game and access the demo on Steam.
