Oneiro Free Download (v1.3c)
Game Overview
With your mind saturated with horrors from your caretaker, venture to the depths of your nightmares to overcome your fears. Lucid Dream the 4 Layers of your Labyrinth to reach the end. Each layer gets progressively more difficult and is meant to test your knowledge of the games mechanics. Collect/duplicate items, find powerful weapons, and use gear to conquer your Labyrinth. Fists, Swords, Karambits, Hammers, and Spears. Out of these, players will be able to find a weapon that suits them the most. Each of the weapons are unique in their own ways, and diverse enough to keep combat fresh and engaging. Oneiro allows your creativity to shine at any given moment, and nearly every object and mechanic have multiple purposes. You may want to go right up to an enemy to fight them; or perhaps you’ll want to use throwing knives to destroy a nearby wall and collapse the ceiling onto them; maybe you’ll break through the ceiling and attack them from above. Items are normally found through treasures, and they play a major role in Onerio by improving the players stats, or granting new abilities. All items can be stacked to multiply their effectiveness, as well. If the player wants to focus their duplications and have 10 midair jumps, or regenerate 20% of their life every 10 seconds, or even causing enemies to explode in a large radius upon death; nothing is stopping them from it.
