It's been two weeks since the release and I'm still thinking how to improve Hack Grid.
I was asking myself, how could I make it more retro? 
After all, the game is a love letter to DOS-era gaming.

As a result of thoughtful thinking, I started playing around with a CRT shader!

I just uploaded the newest version of Hack Grid which contains the sweet old-school CRT effect!
You can see it on the screenshots.

If you don't like it for some reason, you can turn it off in the settings.
