A simple match-3. It's often said that match-3s practically write themselves, but that only applies if you can stop yourself from playtesting them repeatedly.
The controls should be self explanatory. There's a handful of different game modes too, including a "zen" mode for chilling out (or panicking if you fancy setting the difficulty a bit higher) and a Dr Mario inspired stage based mode.
You can switch the music off via the menu.
