Has an interesting gimmick and some nice music scattered around but it's countered with being uneventful and having bad sfx. There are countless instances of just pure empty space for upwards of 30 seconds, and as a result it just makes the whole product feel kind of half-baked. Quite mediocre overall, but there's potential for something better.

Word of advice, do not bring the 3-way spread shooting cyborg (supposedly named Mars) to the penultimate boss. Its shots don't go on past the boss' shields and then that shit becomes a herculean task.
