I'd give it a C. Aside from the length, it managed to be confusing, feature irritating characters and overall was just rather silly. I thought it looked ugly too. I also don't see why all the jumping back and forth in the timeline was necessary except for that kind of thing seemingly being 'hip' nowadays.
I played the iPad 2 version. Initially, I was very impressed by the graphics, story, acting and game mechanics. However, progressively the game got bizzare, really weird. I started giving it an "A," but would end up a "C" given the silly story and length. I believe the iPad version has the same storyline and length as the PC. I was glad it was only $4.99 and have deleted it.
It's also in my yet to be played pile. I'll probably enjoy it since I tend to like "weird" things, moving in time appeals to me, and I've enjoyed every single one of Pendulo Studio's games so far. On the other hand, I'll probably be put off by the short length, and it may still not make next year's list because of this. I suppose I'll just have to see which reaction is stronger.
Interrogator: [True or false?] All mangoes are golden. Nothing golden is cheap. Conclusion - all mangoes are cheap.
I dont think I used a walkthrough either, (dont think there was one) and it was still one of the shortest full length adventure games Ive played:-) Of course if you do happen to get stuck on a puzzle for 20 hours then that *will* extend the gameplay a bit:-)
