There are puzzle games. Then, there are puzzle games. If you're a fan of having your brain melted, then Noodlecake Studios' new game HueBrix might fit the bill perfectly.
If Tetris, snake, and one of those "unblock" games had a baby, it would be HueBrix. The goal of the game is to "drag paths from block to fill out the puzzle grid." Sounds easy enough, right? Sure, but each color block only allows a path of a certain length and orientation.
