looking for some suggestions

[Target]

for some games for my mother in law 

preferably puzzle or platform/side scrolling games, and nothing to difficult (this is for a person who can't remember a 5 character password from one day to the next)

scrollers should be run and jump or run and jump and shoot (no space games)

oh, and they need to run happily on Win7 X64...

I suspect the old Monkey Island series could be a contender (anyone know?), but this is way outside of my normal gaming preferences so I have no idea

my mom really liked samarost and samarost2.

my mom really liked samarost and samarost2.

yeah I thought of that (actually I saw machinarium in the shops) but I was looking for offline games

and FWIW the idea of her being loose on the net terrifies me...

I'm pretty sure Samarost is offline. That is, once you buy it, you can download it and play offline. Much like Machinarium.

Monkey Island games should be pretty good. IIRC there's no way to die in them. You just need to figure out what to do next.

Plants vs Zombies might be a good one as well.

VVVVVV is a possibility. It might be a little hard though. Luckily there's a demo you can try out.

Ooo...There's a good one that comes with Windows 7. I've lost an hour or two to it once or twice.
