Game is awesome, but dosen’t support all graphics cards.
I’m running this on the new 2015 MacBook with AMD Radeon R9 M370X 2Gb and it plays well up until the underwater sequence. After that hits, the game is basically unplayable. I believe it is an issue with graphics card support. If you go into the package contents of the application in the resources folder and change the undergrowth folder to _undergrowth it will remove the glitchy graphics but add a slight lighting issue. It will definitley make the game playable again though.
