I bought a dangerous surgery after dying of reduced health stat, which increased my health to above average. Unfortunately, I stayed dead. But I did get a new girlfriend.
You can achieve a rather odd effect while customizing one of the band members. If you switch them to depressed, then quickly reopen the menu and hover over cheerful, they'll look happy but still say "There's nothing to be happy about."
You can open the storm drain over and over again with the knife. A new grate appears in Johnny's hands, then combines with the existing one. I think Johnny's mastered the multi-verse.
One last thing: In any table top RPG, any fighter will tell you that a hammer is really a very heavy set of lock picks. We have a hammer. The first instinct of many a player to many of these problems will be to smash the obstacle with said hammer. That's probably why a screwdriver and screws are usually used instead of a hammer and nails for that particular puzzle.
Why is it magically impossible to use a mop as a lever, but not the wooden handle after dissolving the head with a mysterious liquid? And if the barrel was too heavy to move, how the heck did I lift it up to put a skateboard under it?
Protip for the newbies: I had no idea what was going on the first few games, but you do eventually figure out how this works. It could probably use a better tutorial though...
The main difference between us and current computers seems to be the possible existence of quantum processing in our brains. And even if the state of information in the brain is destroyed, some say it is possible for the quantum information to persist. This appears to be the most scientifically viable version of a soul. If SGDS was also a quantum computer (which seems to be very important to sentience), then it would also theoretically have a soul.
