I’ve been playing PictoQuest and here are my thoughts:
It is picross. If you like those style puzzles, here you will have a collection of them. If you don’t like picross, don’t think that the RPG elements will make up for that. The early puzzles couldn’t be easier; the latter are challenging enough for someone who doesn’t play these style puzzles often. The RPG elements are superfluous. The game looks good and is charming but there is little to it other than playing one puzzle after another. Yes, there are some items, and yes, there are some challenges, usually based on time, but that is about it.
The game is perfectly fine, but when you look at games that combine puzzles with RPGs, this certainly falls below the likes of Hero Emblems, Puzzle Quest, etc.
That said, if you like picross, you’ll get a nice collection of puzzles for $4, I believe.
