A game can claim to be relaxing and then undermine itself in the interface: flashing rewards, urgency banners, loud red badges. The interface is where calm is either kept or lost, and it is made of small decisions rather than one big one.
These are the rules used in Candy Mass, and the reasoning behind each.
Every surface is a deep violet-black. There is no light theme.
This is partly aesthetic and partly practical. A bright interface in a dark room is physically uncomfortable, and a lot of mobile play happens at night. A dark palette also makes the falling candy the brightest thing on screen, which is where attention should be.
The palette is deliberately narrow: four dark purples for surfaces, one gold for emphasis, one pink and one aqua for accents. Nothing else. A narrow palette is what makes an interface look designed rather than assembled.
Gold is the accent colour, and there is never more than one gold element visible at a time.
The reason is contrast hierarchy. If everything is emphasised, nothing is. One primary action per screen — the button that matters — and everything else is secondary surface or plain text.
Applying this rule strictly means deleting things. Early layouts had three gold buttons competing. The fix was not to recolour them, it was to decide which one the screen was actually for and demote the others.
Transitions run at 250 to 350 milliseconds with an ease-out curve. Nothing springs, nothing bounces, nothing overshoots.
Bouncy motion is the visual language of playful games and it works well there. It is the wrong language for a game whose whole promise is that nothing is urgent. Slow, smooth transitions read as settled.
The same applies to particles. There are confetti bursts and sparkles, but they are short, soft and infrequent. Constant particle noise is excitement, and excitement is not the goal.
Every piece of text in the game is sentence case, and most end with a full stop.
"Nicely done." not "AWESOME!!". "That's alright." not "GAME OVER!!!".
This sounds cosmetic and is not. All-caps exclamation is the register of a slot machine. Sentence case with a full stop is the register of a person speaking calmly to you. The text is doing as much work as the colour palette.
Three common mechanics are deliberately absent.
No countdown timers, because a timer turns relaxation into pressure.
No energy system, because being told to come back in two hours is a reason to stop playing rather than a reason to return.
No streak punishment, because losing progress for missing a day punishes exactly the players who have other things going on.
There is a daily reward, and it is genuinely optional. Missing it costs nothing beyond the reward itself.
Cards have 20 to 24 pixels of internal padding. Buttons are large. Nothing is cramped against an edge.
Cramped layout reads as urgent, even when nothing urgent is happening. Generous spacing reads as unhurried. It is the same information at a different tempo.
Before shipping any screen, one question: would a loud game also ship this?
If the answer is yes, the element is probably too much for this one. A gold badge with a countdown, a red notification dot, a bouncing call to action — all of those are correct in a competitive game and wrong here.
The rule is not "make it pretty". It is "make it quiet", and pretty tends to follow.
