This indie puzzle game packs 400 rooms and no combat—just pure challenge

A new indie title called OOLO is shaping up to be one of the more unusual releases this year. Built by a solo developer, it mixes classic puzzle design with Metroidvania exploration—and completely skips combat.

A throwback to classic isometric games

OOLO leans heavily on nostalgia. It uses an isometric camera, a style popular in early gaming that creates a 3D feel using a fixed angled view.

The developer describes the idea simply:

• Inspired by older games like Solstice
• Expand that concept into a much larger modern experience

The result is a game that feels old-school in design, but much bigger in scale.

Over 400 puzzle rooms to explore

Instead of combat or boss fights, OOLO focuses entirely on:

• Puzzle-solving
• Platforming
• Exploration

The game features:

• 400+ handcrafted rooms
• Multiple environments (forests, dungeons, swamps, mechanical zones)
• Hidden upgrades and collectibles

Every room introduces a different challenge, from timing jumps to avoiding traps and enemies like ghosts and skeletons.

A Metroidvania structure without fighting

OOLO follows a Metroidvania design, meaning:

• You explore a large connected world
• Unlock abilities over time
• Return to earlier areas to access new paths

But unlike most games in the genre:

• There are no weapons
• No boss fights
• Progress depends entirely on solving puzzles and movement mechanics

Difficulty options change how you play

The game includes multiple difficulty modes:

Mode	What changes
Casual	Unlimited lives, relaxed exploration
Classic	Limited lives, traditional challenge
Retro	No save points, highest difficulty

This makes the game accessible for casual players while still offering a tough experience for those who want it.

Abilities evolve as you explore

As you progress, you unlock upgrades that change how you interact with the world:

• Move and push blocks
• Gain new movement abilities (like double jumps)
• Use items to solve more complex puzzles

This creates a steady sense of progression without relying on combat systems.

Story: a simple but classic setup

You play as a small wizard on a mission to:

• Relight the World Flame
• Save a world falling into darkness

The story is delivered through:

• Short text segments
• Memory fragments found during exploration

It’s minimal, but fits the game’s focus on gameplay.

Release details

• Launch date: May 20, 2026
• Platforms:
  • Xbox Series X|S
  • Xbox PC
  • Steam
  • PlayStation 5
• Supports Xbox Play Anywhere

The takeaway: a niche game with strong identity

OOLO is not trying to compete with big AAA releases. Instead, it focuses on a very specific idea:

• Pure puzzle gameplay
• No combat distractions
• Heavy exploration and backtracking
• Retro-inspired design

For players who enjoy puzzle-heavy games and classic design, this could be one of the more interesting indie releases to watch.

It’s simple in concept—but with 400 rooms and evolving mechanics, it might be much deeper than it first appears.
