I agree with the comments from other members about this game re: It is a very good game, but I give it , as in another review, a 3.75 stars out of 5 because of 2 annoyances which I personally hope the Devs. make adjustments in the next game of the series if there is one: 1) When you are in an area where there is an *HO it plays an annoying music and continues to do so until you play the HO, this is all and well if one wants to tackle it right away, but if you have just finished one and wish to explore the new area first and do a puzzle before hand, you are distracted by this annoying sound that will not stop, no fun.
2) I have slight eye problems and the constant bright flashing screen while playing some of the mini games and in other areas or aspects of the game, are very hard on the eyes and I had to turn my head away often from the screen, and in some cases hit the solve button, not because the game was hard but just to get away from the flashes.
Is this game replayable despite its flaws, Yes, would I recommend this game = Yes.
*HOs and there are lots of them but again OK because they are varied, fun + a custom choice to make the hint system as low as 15 seconds for recharge = A-OK in my books.
