Minimalistic 3d puzzle with portals, cubes and lasers.
The game tasks players with building correct electrical circuits using a variety of interactive components, including portals, cubes, and lasers. Players must manipulate tiles, some of which can be swapped, rotated, or both, to connect point A to point B and complete each puzzle.
The 77 levels in the game start relatively simple, but Quiet River steadily introduces new mechanics and challenges as players progress. The later puzzles require critical thinking and extensive experimentation to solve, providing a satisfying sense of accomplishment when the player finds the right solution.
Overwhelmingly positive user reviews (99% positive) praise the well-designed puzzles and rewarding gameplay loop. Reviewers appreciate the minimalist aesthetic, relaxing ambiance, and the satisfying feeling of solving the intricate circuit-based challenges, which test players' problem-solving skills without becoming overly frustrating.
The game features 165 achievements that are straightforward to obtain, appealing to completionist-style players who enjoy customizing their Steam profiles. Reviewers also note the game's replayability, as the puzzles can be approached in different ways, encouraging experimentation and refinement of strategies.
For players who find the core game too challenging, the developers offer a free DLC called "OxU Lite" that reduces the complexity of the puzzles. This accessibility feature allows a wider audience to experience the game's mechanics and engage with the overall puzzle-solving experience.
