I've already bought the game, but I lost my download link. Can I get it back?
Yes. Just go to the download page
and enter your activation code or email address.
Can I install the game on more than one computer?
Yes. Each purchase can be used to install the game on up to 5 different computers per month.
This should be more than enough for reasonable personal use.
For each purchase, the web site stores the customer's name, email address, date of purchase,
and country of residence, as recieved from PayPal. This data is used to provide customers with
their download link, to allow it to be recovered if they lose it, and for tax records. For each
install, the game also sends a unique identifier for the computer it's running on (a list of its
MAC addresses) to the web site, which is used to limit each purchase to a maximum of 5 installs per
month. No data will ever be disclosed to anyone, except where required by law. The web site does
After buying the game, will I be able to use it forever?
Yes. The game and web site will be maintained for the foreseeable future. If at some point it
becomes uneconomical for me to continue doing this, I will release the game into the public
I can't solve a level. Can you give me some hints?
Try different things and see what happens.
Look at things in the real world to see how they work.
Energy comes in different forms and can be transferred between them.
Gravity can be harnessed as a free source of energy.
Use motors when you need a controllable source of energy.
Power is useless without control.
Take a break – sometimes ideas need time.

When you ask Lucifer's Atoms to start a network multiplayer game, it needs to talk to other
computers over the internet. By default, Windows Firewall allows through the outgoing traffic, but
blocks the incoming traffic. So if you want to use the network multiplayer mode, you'll need to
click on Allow access.
The game runs slowly.
Lucifer's Atoms uses OpenGL for its graphics. Check that you have the drivers for your graphics
card installed. These can be downloaded from your graphics card manufacturer's web site
I've found a bug in the game.
I'll try to fix any bugs you find. Email me
with a description of how to re-create the bug, and the level that causes the bug, if applicable.
It would be helpful for me if you could simplify the level so it demonstrates the bug using the
Can I make and distribute videos of your game?
Yes. In particular I have no objection to people indirectly gaining advertising revenue via
videos of my game.
Can I distribute the levels I've made?
Yes. You own whatever you create with the game (as long as it is your own work) and you can do
whatever you like with it.
Are there any other games similar to Lucifer's Atoms?
My previous game, Armadillo Run is
similar, but objects are built on a 2D plane and you don't get to control your creations. Here are
some other physics-based construction games you might like.
No. Lucifer means light-bearing – the planet Venus (the evening/morning star) is called
Lucifer, and animals that glow in the dark use a chemical called Luciferase. Light is associated
with knowledge. Lucifer's Atoms challenges players to combine simple objects together to create
more complex mechanisms and I hope it gives them a feeling of enlightenment.
