Nice atmosphere. Fairly simple but there’s nothing wrong with that.
I did find that for me, the bar-parts would often spawn outside of the play area, I think sometimes far enough off that I couldn’t even see them (but often just out of reach behind the rectangular border around the play area). At first I tried to work around it by restarting, but that way I never got past the second one. Then I thought ‘well maybe they didn’t compensate for differing screen resolutions’, so I moved it over to my other window. So I started moving the game back and forth between the two monitors, as the piece would spawn only (and immediately) whenever I moved it to my laptops screen. That way I could finish the game :-)
