So why did they make this game so much longer as opposed to polishing it's overall quality?

Discussion is as the title states. Endless bugs throughout my playthrough. Anyone else find the doorway in the cemetery that just leads you out of the map and breaks the camera prompting a reload? A really stiff combat experience that has not improved at all from the first game if not worse with the additions wherein if you don't know exactly what weapons to be using against what enemies at what times, then you WILL take damage because their animations and overall movement speeds are always faster than you (Dodge or no Dodge - using this mechanic doesn't appear to make the combat any better unless you know exactly which weapons have the best efficacy against which enemies to induce stuns etc). An astonishing decision to remove menu reloading which was always a staple of classic survival horror. (this has irritated me the most with the bad combat) Puzzles are great, if not better than the first. Great context clues and very rewarding to solve. The increased size of the map also helps make it feel as though you aren't just solving a puzzle in one room and then walking into another room with a puzzle. I write this post as I just managed to >!beat the boss in the mass grave!< only to die with both the flashlight and lighter in my hand in the tunnel heading back towards town. Like I died due to the darkness with both sources of light equipped and turned on? How are bugs and mechanics this prevalently jank in a game that the devs spent 4 years on? I rage quit after dying to a bug that I now have to >!redo a tough boss for (idiocy on my part for not immediately saving after) !<and in the midst of my rage I realize that there are multiple areas left and in checking my trophies there's a >!combination key again!< that I haven't even gotten to? Why in the world would they have made the game so much bigger in scale and longer in duration and not polished and cleaned up stuff that would appear to require simple debugging and playtesting? It's borderline embarrassing and humorous that a game that has environments that look this impressive and gets so many tenants of this genre right couldn't just spend the time to play better and provide a better experience. I wrote this on the heels of raging due to my own stupidity and what appears to have been a genuine bug, so it probably comes across really pointed, but this post effectively summarizes my review of the game thus far. To add, I am enjoying the game probably even more than the first. Just frustrated at what I think could have been better.
