Lanternbloom

Tap a firefly to send it to the lantern string. Three of a colour light a lantern, but seven waiting ends the night.

Mouse: click a firefly to send it flying. The buttons around the string undo, restart and show a hint; the sound button (top right) opens the Music and Effects switches, and the menu button (top left) leads back.
Touch: tap a firefly; tap the same buttons.
Keyboard:
In a level: arrow keys or W/A/S/D move a highlight over the board, and Enter or Space sends the highlighted firefly. U, Z or Backspace undo; R restarts; H shows a hint; M mutes.
On a panel: Enter or Space picks the first button that is not an ad (the keyboard never starts an ad); R retries or replays; Escape closes the hint offer.
Title screen: Enter or Space plays, L opens the levels, D the daily meadow. Level select: ←/→ turn the chapter, Enter plays the newest level, Backspace goes back.
