First off, the game is very fun to play and works well, through the whole game I never experienced any lag. My problem is that this is not a full game. It is only one chapter in what seems to be a series of "assignments". ( a fact I never even considered). After having this game for a little less than a day I realized this, after the app told me that in order to continue I would need to download the hd version of the game which is .99, I don't have a problem with the price, the problem is that it was never indicated that this version was as the developers put it, a "lite" version. Had I known this was a trial version , I may not have downloaded it, As an individual not familiar with the company, I find it very questionable why they would use the term hd in the title rather than the general term, lite. It seems to me, that their hoping that by giving people a taste , they'll reel them into buying the full version. Good game but not worth the confusion.
