Nigh unplayable due to completely ridiculous difficulty antics. There's potential here, but the game is so actively working against you at all times that frankly it’s hard to give any credit. This is due to lack of i-frames, randomly spawned enemies, and lack of any lives or continues without hidden codes. There are patches online to mitigate these issues but I'm not here to rate the patched version.

I found the visuals to be pretty lacking as well, and the most recurring song in the game really blows, so all in all the presentation really is not doing it any favors. I'd be willing to forgive it probably if the game was fun or at least more lenient, but in a state that I already heavily dislike it's just another bullet point to add as a reason.

As far as I know, this isn't even a victim of localization buffs. The original release is just as impossible. I suppose it isn't really surprising that the credits are very short and don't list any testers at all, but who knows what good that would do anyway.
