Okay, that was quick. I tried the demo today, and it took me eleven minutes to complete it. There are about ten levels that teach a couple of basic mechanics, and it has four achievements. Also, about one minute was me trying to see if I can run the game in windowed mode or change the monitor it was on. (Didn't find the way.)
The game is about moving characters to goal spaces on hand drawn levels based on a hex grid. Certain features of the levels have color that causes them to behave differently depending on whether the character attempting to cross them has the same color or not.
You start with red and blue types, and later the demo introduces purple characters and then the ability to combine one red and one blue to a single purple one, and split it back to two characters. Purples work like both reds and blues in certain ways.
The story is told in short texts between levels. It didn't tie into the puzzles in any way in the demo.
It can turn out to be a good puzzle game if the puzzles get harder and there are more elements in the full game. If you don't mind it being short, you can try the demo yourself. I tried not spoiling the details of how the elements in the demo actually work
My verdict? I'll keep an eye on it. Whether it's worth getting depends on how much puzzle content is in the full game.
