Made in 48 hours for Ludum Dare 45 (theme: "Start with nothing").


In quantum physics, a particle and anti-particle can be created from nothing (sort of).

In this game, the goal is to place a pawn on every goal space. You can create a pawn from nothing, but you'll have to create an anti-pawn too, which moves backwards and annihilates pawns that it touches!

Use the pawns and anti-pawns together to progress through the game and solve tricky puzzles!
