Joules are a measurement for transfer of energy. I used it because it applies to both kinetic and thermal energy transfers so that I could keep asteroid impacts, plasma weapons, and torpedoes all on the same unit of measurement for damage. Although looking at actual energy tables, I should probably be using Terajoules, but it mostly just so you have something to compare values with.
Too many people are giving this negative reviews and comments. Sure it is way too easy, indeed it may be just spamming satellites, and of course the AI needs a little work BUT, remember that this game was created in 48 hours AND required a knowledge of orbital mechanics to implement so if u think u can do better then try to do better, otherwise, SHUT UP AND ENJOY IT.
suggestions: bees interact with or create wax in the shape of a hive. acorns that become trees. lava beats virus. acid evaporates. acid eats metal. water conducts electricity but not as powerfully as metal. melting metal. tutorial/brush preview. birds that eat bees and ants.

I followed up and maybe you can benefit from what I told him? orbit is possible.
