Steam Version has Stretched HUD and bad FOV for 16:9 Aspect Ratio

[Simian]

Hi, I just bought this game on steam and I was troubled to see that it does not work properly with widescreen aspect ratio. The HUD is displayed stretched horizontally, and the FOV is zoomed in much too far. I heard that a patch was released to fix these problems, but it does not seem to be working for the Steam version.

I tried to take screenshots of this, but the screenshots don't save.
EDIT: I was able to take screenshots by activating the Steam overlay and using its built-in screenshot manager.

Here is the game in 4:3 (1280x1024)
Here is the game in 16:9 (1920x1080)

As you can see, the top and bottom are cut off in 16:9 making the game zoomed in, and the health/warmth meter is stretched to an oval shape.

Please tell me how I can fix this. Thank you.
