Keystones

[i]Keystones[/i] is a casual puzzle game about matching blocks based on their color. The target in every level is to set all the movable blocks on top of the fixed ones, by matching their color. When bicolored blocks enter the equation, things complicate a bit because you will need to find the right arrangement of blocks, given that the top block and the bottom block need to have at least one common color. The levels range from trivial (introductory levels that show / teach the game mechanics) to average and in the end towards challenging. There is always a logical approach to solving one level instead of brute-forcing all the possible combinations, but the last 5-7 levels are still a bit demanding, even with this logical approach. https://steamcommunity.com/sharedfiles/filedetails/?id=1692606846 I enjoyed playing [i]Keystones[/i], and especially figuring out the mechanics of the end-game levels. Two fixed blocks can have a link between them, which means that the movable blocks that come on top have to match the link color in the half that is oriented towards it. In some cases, this link disappears if a block matches its color from one side (there are arrows to indicate this) aft…

Simple and fun puzzle game. Later levels are quite hard to get it perfect. But really cool.
