I need to know if it is working fine on Windows 10

It looks like this game could benefit from having some Steam achievements. Are there any plans of adding any?

What is tue key to exit? Esc doesnt work

The store page images all show the game in widescreen format (1280x720 images), but on my computer, it's displayed in 4:3 aspect ratio -- a window with 4:3 aspect ratio, or full-screen with black bars on the sides. It's not a big deal, but is there a way to make it widescreen?...
