submachine was quite good.. got stuck after 20 minutes or so.
I got stuck in less than 2 minutes. I'm not sure, since I didn't get far, but I think the game lets you do stuff that breaks it. The first thing I did when I played was enter a number into the device and it broke into pieces. Then I couldn't do anything else with the machine (or its pieces) so I'm guessing I did something wrong with it?
Then I found a couple pieces of jade and put a switch back into a wall and flipped the switch (which didn't seem to do anything) and that was all I could figure out to do.
