Humongous makes computer games for children. Their main group of games are adventure games. They are all well written and illustrated, full of interesting puzzles, some education material, and generally a lot of fun for kids too.
The only problem is that, this time around, the game was too easy. It was marked For Ages 7+ so I figured my 6 year old would be able to do it but possibly with some difficulty. He did have a couple of problems but I only had to nudge him a bit to get him back on track... and he finished it in basically one solid day of playing.
That's half scary and half disappointing. I think this Spy Fox game was shorter than average, but I also think he's gotten much, much better at these games. I'd have to give Spy Fox: Operation Ozone only a 3/5 because of its lack of length.
I dunno. He's definitely smart, though.
