It is the beginning of the universe, and it's a tough place to live. War rages on between matter and anti-matter as these two equal but opposite forces fight for dominance in the universe.
You play as a quark trying to survive within this turbulent world.
In creating this game, I utilised some fairly simple physics of electromagnetic force to create interactions between particles. When the particles collide, the effects are all valid interactions.
There are, however, some inconsistencies:
1. Today, quarks are never found on their own in the universe and thus never interact in this way. Whether they did interact this way before protons and neutrons were formed (ie. right at the start of the universe) is open to debate (as far as I know).
2. There are no strong, weak or gravitational forces used in the game. However, we currently don't know the exact configurations of the forces at the start of the universe, so I'm not going to lose sleep over that one.
3. There are probably other interactions that I missed. Whoops.
In any case, I hope this is a fun game to play. Please leave some comments if you notice any issues and I'll do what I can to fix them (or at least I won't make the same mistake for my next game...).
