I played through the online version quite a long ways, and got to phase 3 but managed to bugger up my game, and since it took me so long to get  there I haven't tried again yet.

The game is mostly accessible, but several things you need to click on like the stock market don't have a clear layout, and quantum computing doesn't really work the same way either, I didn't exactly work out what yomi stratogies did, but a lot of things are relatively easy to get with a bit of practice, EG with the stock market which is bloody complicated, just buy stocks and then wait to see until you make a prophet and hit sell, and ignore all of the columns of ever changing numbers, just concentrate on how much you get back.

also there is The universal paperclips wiki found here if your stuck.

To answer mirage's questions, operations are your basic resource that you need to do stuff, like complete projects such as buying more autoclickers etc.
Memory lets you store more operations, while processors increase the speed you get operations at, though you need more memory than processors and there is a limited amount of trust available so you need to be careful.

At the beginning concentrate on selling paperclips, buying wire and upgrades, and gonig from there.

As to why the resource you need to upgrade yourself is called trust and what happens when you get enough of it, well that's an interesting thing to see .
