Great Permutator

I like the concept, but other games do it better. If this sort of thing interests you, check out something like Shapez instead.

+ Difficult puzzle game - No interface explanation. (protip you can toggle which side the switcher starts on). - Extremely difficult - Not that satisfying when you do get a level, as I found it was mostly trial-and-error or playing with the length of converyor belts to create interleaves without clashes. It's often hard to conceptualise how to chain 3 switch blocks etc. I bailed on level 15. I only "recommend" it if you like a really diffiicult challenge. If you like a normal challenge, wait until it's £0.50

Pros: Pleasant music Challenging puzzles Leaderboards Colorblind mode Cons: UI could be better

A hidden gem! A real workout for the brain :)

Great little puzzle game. Some of the puzzles are really challenging, making it really satisfying once you finally solve them. I still haven't managed to solve them all, but thankfully it's the type of game where the mecanics are easy enough to understand, even though the puzzles are really difficult to solve, that I can get back to it at any time to try to progress further. The puzzles can be solved in many ways, allowing you to experiment to find better solutions and climb your way up the leaderboard. The game also contains great achievements that not only track your progress, but also ask you to solve puzzles in different ways to complete extra challenges.

Absolutely love this puzzle game. Hope to see many more games from Artem Ripatti

第一页全A+，不太打得动了。真心良心游戏，设计逻辑线路并在有限的空间里放下它，然后为了A+还要优化生产线路（对我来说A+就够了最优解啥的还是算了......）总之是个很好的工程游戏 顺便随机器是完全非随机的，随机数种子由路径唯一决定，所以人品毫无作用...... After several hours of play I get all A+ on the first page. On the second page introduction of the fuse-and-change machine greatly increased complexity so I decided to drop. Actually for an engineer A+ is good enough so I never tried to find the global optimum solution. Also, randomizer is not random at all. Rebooting Windows or even play the game tomorrow will not change the result. The seed of random number is purely based on the path that the boxes take. So neither luck nor replaying the level will help with randomizer level, which does not sound like a real randomizer for me. 10/10 for workflow (they really "flow" on the conveyor lol) design and the price
