Man, scientists. Haven't you ever heard of placing an ad in a university newspaper advertising your physics research study? Tell people they get to play with a matter-absorbing gun and they'll probably pay you to participate. Why ya gotta be all evil and kidnap a guy to send through a nefarious set of puzzles? The mad scientist villain of Absorption, by Anton Beluzhenko, isn't very smart, apparently. But the backstory isn't why you'll want to play this game. Absorption is a novel and unique platform puzzler that is a lot of fun to play.
You use the [WASD] keys to control the platforming action of your character, while the cursor aims your matter-absorbing gun, which you click to shoot. You'll need to absorb and rearrange various objects to solve puzzles and reach the exit of each level. You can only shoot within the "halo" surrounding your character (the cursor will be bright green if it's within range), and you can only absorb objects that have little white orbs rotating around them. In addition to testing your spatial intelligence when using the absorption gun to rearrange objects, the game also sometimes requires good timing, particularly in terms of dealing with enemies. Just try to get to the exit with as few shots as you can. At the bottom of the screen you'll see what number of shots will give you a 100% efficiency score.
Anton makes a good choice in giving you unlimited shots while also rating your efficiency at the end of a level based on how many shots you used. This means you're free to experiment your first time through a level, and you can always replay it to try to get 100% efficiency if you shoot too much the first time. The portals, boxes, turrets and other elements of the levels give plenty of variety while still being fairly intuitive and thus not overwhelming. And when we're talking about pluses of the game, we shouldn't leave out the fact that the little guy kind of looks like he's from the movie GhostBusters. Who ya gonna call? Absorption!
