This is a neat little game idea! The dialogue from the Big Guy was a nice touch. I'm not sure about other users, but for me, the CRT and static filters are obscuring a lot more of the screen than is shown in the screenshots you provided (I'm using Google Chrome on MacOS if that's of any help). Similarly to alpikespot, I also was unable to get past level 5 because of the screen effects.
Despite those issues, I think this was a nice game overall!
