A couple reviews of random games from the Humble Freedom Bundle (curious what else I should be playing from that package, since it added like 100 games I've never heard of to my Humble library)...
Mini Metro - does this gif look like fun? If so, you'll probably enjoy it!
You start off with a few stops (a triangle, square, and circle) in a city, and you draw subway routes to connect them. Passengers show up at your stations trying to get to other stations, and you draw the network that will get them there. Over time new stations pop up and with a limited amount of resources (trains, and tunnels/bridges through water) to use, you'll try to get everyone where they want to go without stations getting backed up with angry waiting riders.
Can be enjoyed in small increments, kinda fun, would pay $1-$2 for it if I didn't get it in a bundle.
Human Resource Machine - this is basically a programming game like TIS-100, but with a friendlier interface and abstracted into a mailroom. I think it's by the World of Goo people judging from the look and feel of the game. You get inputs in one side of the mail room, and put outputs in the other, and perform operations in the middle that you define by constructing a program out of instruction blocks that basically mimic assembly language - load, store, jump, add, etc.
If you like programming games I think you'll like this, I just got started with it last night and enjoyed it a lot. In 1-2 hours I got through like half the puzzles but I suspect I'm just now getting to harder ones that will take a bit longer to complete.
