If you fancy something small, pleasant, and mildly challenging - yet cheap - this weekend, you might enjoy a look at Klocki [official site]. It's a clean and calming £1 puzzle game about moving and swapping tiles on shapes to connect and complete the lines etched into their surface. That's all. I've been enjoying it.
This isn't one of those awful sliding block puzzles (the bane of survival horror!), to be clear, but simply picking up and swapping a pair of tiles by clicking on them. A bit like Loop, except not with loops. It starts simple, with straight lines on simple shapes, before introducing odd shapes, multiple shapes, curved lines, lines across several planes, tiles which behave in different ways, shapes which behave differently, and so on.
It's not huge, taking maybe an hour or so to complete, but it is pleasing. Simple ideas are introduced, demonstrated, and then folded into larger puzzles with multiple elements working together.
It's quite pretty and makes calming noises too. That's nice.
Klocki is out now on Steam for Windows and Mac, priced at £0.71/0,89€/$0.89 including a small launch discount.
