The concept in this fourth puzzle game remains the same: find the star in each of the 16 main levels and unlock 9 extra levels by completing rows and columns that appear on the main page of the game.
No more black and white graphics in this new installment, the color is now officially part of Hoshi Saga series!
Unfortunately, if Hoshi Saga 4 looks great, it is definitely on the easy side. If you are looking for more challenging games, give a try to the previous installment in the series!
