Get Rich Efficiently by CobaltRisen
In Get Rich Efficiently, you are given $1000 and a small amount of land which contains valuable gold. You must figure out how to start a mining operation to extract this gold in the most efficient and compact manner possible. But beware, it takes power to export this gold to the rest of the world, and so you must be careful to keep your power from running out. In the beginning, you will only have solar panels, but as you progress, you will gain access to steam engines, and will eventually be forced to set up the infrastructure needed for them. Filling the world with solar panels just won't cut it once you have too many mines for them to keep up with.
A Decent Mining Operation:

Controls
Left Click - Place whatever you have selected
Right Click - Destroy what your mouse is over (Gives you half your money back.)
(Pretty simple, right?)
Basic Tutorial
First, place four solar panels in a line near a patch of gold and run power lines so that each solar panel is adjacent to a power line. (Most everything can interact with a power line on the 8 tiles surrounding it.) Power lines only connect to each other in the 4 cardinal directions. Place a mine on a gold tile, and connect it to your power network. The "!" should disappear when the mine gets power. If you hover over it, you can see the mine's progress and power consumption. Other machines will behave in a similar way. You should start seeing gold be added to your inventory while the solar panels are generating power. Solar panels are useless at night. Placing a gold seller beside a power line will start to sell gold from your inventory for $10 a piece. 1 of these can keep up with two mines. Be careful, to sell gold you need power, so if you run out of power, you won't be able to sell gold. You now have a basic mining operation that will mine and sell gold during the day. Now the rest is up to you. I suggest adding another mine. You may need more solar panels to power it. Good luck.
How to use the steam engines
As almost every single comment so far has mentioned that the steam engines are confusing, I may as well talk about how they work. Pipes are used to transfer fluids and behave similarly to power lines. Boilers take coal from your inventory, and when fueled will heat your pipe network by 20 degrees each. They don't connect to pipes on their bottom face. Steam engines are what make power, and require 100 degrees of temperature and 10KL of water each. Water's standard temperature is 20 degrees with no boilers, therefore you need 1 pump and four fueled boilers for the first steam engine, and 1 pump + five boilers for each additional one. If there isn't enough power or fluid available, a machine simply won't run.
Tools/Languages Used:
I plan to continue developing GRE, so if you have any suggestions, let me know!
Updates
- Fixed boiler price mismatch (Thanks @brazmogu)
- Made Power and Fluids easier to read from pipes and lines.

One detail: the Boiler actually costs $100 and not $50 :P
Can you remember what caused it?
Edit: I found the issue (I'm pretty sure) and fixed it.
It reminds me to Sim City and Factorio :D
Congrats on getting a game with a good level of complexity completed within a short timeframe. Plays as well as expected, with some nice clear graphical assets in use.
Great entry, congrats!
Remind me of factorio !
Now, I am almost out of space to build. >.<

You are the winner the following awards:
- 1st Place: Game I've enjoyed the most in Ludum Dare 39
- 1st Place: Game I've played the longest in Ludum Dare 39 (about 2 hours)
- 2nd Place: Ludum Dare game I've played the longest since Ludum Dare 27
Seriously, I really, really liked your game. (I must admit, that I love base-building games and the mechanics they use, so I might be more enthusiastic than most other players.)
You've distilled down the principle of "just one more thing" to the bare minimum. Graphics are just complex enough so you can distinguish between buidlings. Number of buildings and complexity of the map is perfect. The day-night cycle is perfect to get the player hooked ("just one more day").
Of course it would be nice if you could do more :P then I would play even longer ;) The graphics for the mine and the gold seller are a bit too similar, mostly if they are covered by the "no power" exclamation mark. The "remove" feature with the right mouse button feels wierd, kind of delayed, I'm not quite sure why. Dispite your description on this page it took me some time to figure out how pumps work, it's kind of hard to see that they pump 5 water per side that is open to the lake. Also as pipes connect pumps together, I first assumed that water could flow through pumps, which it can't.
Also the "can't build here" sound doesn't quite convey "you can't build here". And in general, a bit of music would be nice :)
Anyway, I'm really impressed by what you've achieved. Congratulations!
