SPRITELING

An egg hatches. Over the next half hour or so it grows through Baby → Child → Teen → Adult, and what it becomes depends entirely on how you raised it. Feed it, sweep up after it, play with it, train it, put it to bed at night. Neglect it and it becomes something else — still yours, just harder.

There are 16 forms to find. Most players will see four or five in a lifetime.

The loop

Feed — four foods. Cake makes it happy and heavy; greens do the opposite.
Clean — messes appear. Leave them and it gets ill.
Play — guess which way it will turn. Five rounds, happiness for each match.
Train — a timing game. Raises Power, Guard or Speed, and steers its evolution.
Battle — turn-based duels against wild spritelings. Bloom beats Storm beats Ember beats Bloom.
Light — at night it calls for you. Turn the light out and let it sleep, or it counts as a slip.
Medicine — cures illness for 8 coins.

Time runs at one game minute per real second, so a day passes in 24 minutes and the sky, the stars and its bedtime all move with it. Close the tab and it keeps living — when you come back it will have got hungry, but it puts itself to bed while you are gone.
