Remember when they gave that out for the 12 days xmas thing for free. Still need to play it.
Went for broken sword the woman has the most annoying voice I've ever heard fake French
Broken sword is amazing. The second one is also out, though I'm not sure if it's on iPad, deffo iPhone. If your mum likes that, as above she'd probably like Monkey Island. It's a bit more darker humour though, but equally as fun.
There's lots of room escape games as well.
Would she be interested in the usual Plants v Zombies, Angry Birds etc?
Try Space Quest and Gabriel Knight.
The Room is fantastic.
How about The Walking Dead too?
