This game is so much fun. I found myself sinking over an hour into it just trying to beat my last score (Peak score was around 3500). Hitting big combos really felt satisfying. I'd say the only thing that took me out of it, was when I would place a tile down, then the very next tile ends up being a much better option for the space I just filled. I don't know if my luck is just bad but that happened so often. I respect that it's part of the game, but if there was another game mode that showed you what your upcoming tile is, like Tetris does, that would be even more enjoyable.
Overall amazing job on making an endlessly addictive game!
