How to play Bloom on Mac

"BLOOM is a fast paced frenetic action first person shooter indie game inspired by the classics like Doom, Quake, Blood, Heretic, Hexen, Duke Nukem and the rest of the `90s FPS giants. Simplistic, nononsense, shoot everything that moves. Three episodes with tons of actions, dozens of monsters, over a dozen of weapons, secrets and everything you'd expect from a retro shooter game. Two-handed sword, gauss crossbow, pistols, sub machine guns, pump shotgun, double barreled shotgun, rifle, laser, minigun, plasma gun, grenade launcher, bazooka, ray gun, chain lightning gun plus a few secret weapons will be your tools of dealing with demon summoners in dark forests, toxic caves, concrete tunnels, castles, demon realms, spilling rivers of pixelated blood to heavy metal tunes!"
