Randomly closed itself, but not often enought to cause a problem but make sure you save often.
Also I played the Original Version not the DC.

Limit to 30 fps

Fully playable with only minor issues.
Icons didn't scale, disproportionately small at 4K. Text rendering broken on augmented resolution
In fullscreen, screenshots taken with printscreen (shotgun) were blank, but Steam screenshots with F12 were fine.
This report is for the Director's cut version, but I tried the original too and it seems to work fine.

Decreased sensitivity on right analog to 120 for smoother joystick-mouse movement
Don't switch resolution from Fullscreen to Augmented after starting a game, it will cut off the mouse area and you won't be able to reach the bottom 1/3rd of screen anymore even after restart. You can fix it by temporarily binding Alt + Enter to some buttons and triggering it twice to toggle the windowing mode or fully deleting the game data.
Default mouse controls are way too sensitive
