This was an entertaining game. Not a game I would normally choose to play.
The Sound Effect for when the board expands ::skull emoji::
I feel that the gameplay is very fair overall. The mouse dragging mechanic is utilized very well. It's nice that the game is not difficult but has a difficulty to it at the same time where it is up to the player to feel that difficulty by choice. It doesn't demand anything from you but instead rewards you for your persistence, attention, and speed if you can adapt to the difficulty that dynamically presents itself over time. It has a dynamic learning curve that grows with the puzzle due to the integrated new types of possible matches. This is both frustrating but refreshing. I can only assume people that enjoy these types of puzzle and matching games would appreciate the fact this game grows over time and there is always a new bar to master in a way that is not punishing.
I personally really liked the music choice.
