It's a good puzzle game with a lot of modes like going for a high score, time attack, no lose condition chillout mode, and local multiplayer. I was sad to see Steam label it as a spam game (profile features limited). What the store page doesn't say is there's a rudimentary online leaderboard and local leaderboard, so you can grind to become top five in the world or top five at home (the rankings only show top five). To keep things simple, you have to slide rows and columns of boxes to create +'s of the same color. You can get it on Steam, Nintendo Switch or Itch.io https://maxkrieger.itch.io/crossniqplus or you can try the original version here in browser which I didn't know about until posting this https://maxkrieger.itch.io/crossniq .
