For people who'd rather have a single - color smartphone, HTC offers
an entirely gold model, and an entirely gunmetal grey model which should be familiar to those with a grey M8.
It would be easy to have come up with «roguelike plus rhythm» and end there, but tweaks to the
model include compressing the game into four distinct worlds (so you can achieve some progression even if you don't beat the game first try), adding new characters who change the structure (one has no weapons; another can not pick up
gold) and breaking out boss battles to a separate level
entirely.
