Oni has crafted a brutal, beautiful, and bewildering puzzle box. Version 16e polishes the edges without dulling the blade. If you enter the dungeon, enter with respect. The environment evolves. The enemies adapt. And if you hesitate, you become just another genetic template for the next blob that comes along.
9/10 (Survive long enough to rate it yourself.)
You are a Blob . You have one slot: "Cytoplasm." You cannot hold weapons. Turn 5: You find a wounded Bat . You kill it. Evolution prompt appears: "Absorb Echolocation? (Replaces Sight with Sonar)" You say yes. You are now blind to color but see through walls. Turn 20: A Troll smashes you. You survive with 2 HP. You flee into a water tile. The troll follows but cannot swim. You kill it via drowning. Evolution prompt: "Absorb Regeneration? (Requires removing Echolocation)" This is the new v16e trade-off system. You cannot have both. You drop sonar for regen. Turn 100: You are a Troll-Blob . You now have 3 slots: Regeneration, Thick Skin, Acid Spit. You are strong, but you missed the secret "Cave Fisher" evolution on floor 2. Why? Because v16e adds timed mutations. You only had 50 turns to absorb the Fisher’s web gland. You failed. Result: Death by Spider Queen on floor 8. “You evolved poorly.”
Unlike standard roguelikes where you pick a race and class at the start and stick with it, Roguelike Evolution allows your character to mutate, absorb traits from fallen enemies, and even shed their original form entirely. You begin as a simple "Primordial Ooze." Every time you defeat a unique creature, you have a chance to splice its DNA into your own, swapping out limbs, organs, or cognitive functions.
If you are a veteran dungeon crawler who cut your teeth on NetHack or Angband , or a newcomer curious about the genre’s evolution, v16e is the patch that changes everything. Let’s break down why is being hailed as a masterpiece of systemic design. What is Roguelike Evolution? Before diving into the specifics of v16e, it’s crucial to understand the scope of the base game. Roguelike Evolution is not a traditional dungeon crawler. As the name implies, the core mechanic revolves around adaptation and metamorphosis .
