Very janky.

Poor controller support - DS4 directional input keeps getting canceled, making the game unplayable.

No borderless fullscreen, so if you have multiple monitors you are stuck playing the game in a window, as otherwise it rearranges your whole desktop. Even if you provide your own  fullscreen solution, like BG or Magpie - the game breaks those as well by constantly resetting the window.

Even though the option is in the menu, there is no way to turn off faux "scanlines".

The load times are insane for a game of this caliber. It literally takes a minute to get into the game, and about 10 seconds every time you lose a life!
