Couple small fixes with steam

Endoparasitic

Three limbs ripped off, infected with a deadly parasite, you must save your research. Drag yourself through the corridors of a secret research lab on a remote asteroid, fight off horribly mutated monsters, inject countless syringes of vaccines, and survive at all costs.

Changed 'Hunter' achievement name to 'Medieval' on steam to match name in-game Changed launch path for mac on steam, fixing the double-click bug. (If you're a windows user setting up a mac build on steam, make sure you point the launch path at the bundle 'Game.app', not the executable in it lol)
