A sliding-merge puzzle: flick to slide the stars and merge equal ones into a bigger one, from a pebble up to a whole cosmos. 30 goal stages with rocks and head starts, plus an endless mode.
How to play
Phone or PC: swipe or drag anywhere to slide every star that way. Keyboard: arrow keys or WASD.
Two equal stars that meet merge into the next size. Reach the stage's goal star; some stages limit your moves.
UNDO, RETRY and MENU are the big buttons at the bottom.
