Hoshi Saga

The first in the Hoshi Saga series, this game sets the basic premise for all
that follow it: it presents players with a simple challenge — through
numerous disparate and unrelated Flash minigames, in each of them the player’s
goal is to use the mouse to reveal a 5-pointed star which is hidden there
somewhere. Across 36 different black-and-white levels, the basic rules of
interaction are different in nearly every screen — sometimes the star is “out
of scope”, which needs to be rotated or adjusted; sometimes it is obscured by
other objects also on the screen. In some screens the player needs to “draw”
the star themself, in positive or negative space. Each level is completed upon
the revelation of its star, and upon the completion of every 5 levels, a 6th
bonus one becomes available.
