A must to pass.
Pros below:
A truly legendary game, where the idea is excellent and the execution is on top. They don't make games like this anymore. Keeps chained to the screen until the end of the game, completed in one go.
Different cons:
As already mentioned in other reviews, the passage of a sinusoid, then silence, then a flurry of opponents. Either the opponents are far from you, or the fat half-boss jumps out from around the corner.
I went through it about 6 years ago, I don’t remember…
