A to B is a minimalist physics puzzler in which (as you might expect) your goal is to get something from A to B -- in this case a ball. Each level gives you one or a set of tools to place in space: walls, trampoline walls, a speed booster or reducer, and a thingie that flips the direction of gravity.
Despite the stark, empty nature of the environment, it's tricky to solve each level, but by no means brain-curdling. The one bit that seems a bit counter-intuitive is that when you start the system moving, the ball launches as if tossed up in the air -- and you have no control over direction or power. Your only means of manipulating the system is the placement of tools, which is okay, but it's not always feasible to anticipate the direction or power of the ball's initial launch. You pretty much have to do a first try to gauge this before solving.
Level score is based on the number of tries (each try reduces it); while there's a high score, there's no in-game save, which is annoying, as you have to restart from the first level if you return.
