Flux Caves
Flux Caves is a 3D puzzle game. My plan is to create something which can be a challenge, but still you enjoy to play. I want to create a soothing environment and this is enhanced by slow piano-based music.

About Flux Caves
Fix the energy pipes so that enough fuel can reach your spare spaceship, and you'll be able to fly away.
The goal of Flux Caves is for the player to have a peace of mind at the end of a hard day. In this game, there is no losing or dying; here, you can discover peaceful caves and open-world puzzles, all while listening to soothing music and working your brain muscles.
Game runtime is 180-240 minutes.
The game made by a single developer
The game was made by one developer, Zsolt Várady alias fubenalvo, who developed Flux Caves in his free time. So the result is not perfect, but there's are no known blocker bugs. I hope you will enjoy it! ;)
