As a joke game it comes across at 3.5/-4 out of 5.
As an actual game it's more along the lines of a 3, you get 1 life. Even most 90's games didn't get you that hard of a time and those that did also let you build up some before that one. Here you are facing something with what seems like basics vs a ohko, got to stage 2 and got bored since all it takes it 1 hit and oh look back to 0. Really inspires me to keep playing.
The few saving graces came from the music and the jokes beyond that..it's eh.
