Haven't gotten very far in it yet... but a few notes so far:
- Mac version says it's not optomized.
- Gamepad controls don't work for me. I can move, but none of the action buttons work, so I had to switch to keyboard.
- Keyboard controls aren't listed. I figured out space/enter is interact and shift is run, but I couldn't find the shoot button. First zombie killed me because I can't shoot. The splash screen input listings aren't helpful either, I eventually found right-click to aim even though that's not listed in the controls.
- Rebuilding the game with a newer Unity version to optimize it.
- Use the InControl asset for (almost) universal gamepad support.
- Get rid of the splash screen, make an in-game menu to change graphics settings and remap controls.
