The boomerang seems like an incredibly useful weapon, being the only ranged reusable weapon in the game so far. Using it is, however, a (quite literally) a pain in the ass, as the weapon has a nasty habit of hitting yourself when returning. How do you catch the returning boomerang properly?
The boomerang will always return to you, so there's no point in dodging it. To catch it properly you need to hold down Space when it's near. This will prevent boomerang from hitting you in the ass, and reduce its wear by half.
