The first Still Life wasn't much problem.
The robot puzzle required timing, but I used the instructions here

It would probably be a bigger hassle if you worked all that out yourself.
I wouldn't recommend Still Life 2.
Very clumsy game compared to the first.
Don't buy a disc version of the first Still Life -- it's crippled with S***Force and won't work on Windows Vista/7/8/10.
