Got to 115 on my best run. Not the beaniest booper around but I'm still proud.
I haven't played the original, so I can't really comment on how well you recreated it. It felt a lot like an arcade game though.
Two things I noticed: First, sometimes enemies would get stuck on one of the lowering rectangles and get pushed out of the screen in helpless despair. Second, I died a couple times because enemies spawned into me, or immediately next to me so I had no chance to react. Other than that, I didn't really find anything wrong. I had fun with it.
