Flux Caves is like playing with a massive set of marbles, only someone came along and pulled a bunch of pieces out and you have to put it back together.
Quite a relaxing puzzle game, not too taxing on the mind and it's quite nice to look at too. Watching the balls roll through the tunnels, as you appreciate a job well done on fixing it. It released earlier this year and it has Linux support, however like a lot of indie games it flew under the radar for most. Not seen it? There's a brief trailer you can see below:
It's not a particularly long game either, it can easily be beaten in only a few short hours.
The developer, Fubenalvo, has now decided to make it temporarily free on itch.io to download and keep. No catch, grab it, keep it. It will be that way until New Year's Eve, although you can donate to the developer if you appreciate it.
On Steam, the game price has also been reduced to £0.79/$0.99.
