Gameplay: the bones of the game are very solid, traditional space shooter gameplay. but there are long stretches where very few enemies attack you. the ones that do attack you tend to follow very repetitive patterns. one of the bosses has a laser beam attack that swallows up a 4th of the screen and there is little to no telegraphing for it. to have any chance of avoiding it i just kind of had to get a feel for the timing. thankfully the timing seemed consistent. i feel bad having bad things to say about the gameplay as it does feel good when all of the stars align, when your blowing things up and dodging attacks. unfortunately that took up a fraction of my time playing it. the game crashed at about level 16 and i felt no motivation to keep playing it past that.
Graphics: very stylish and cool, leaning well into that monochrome old school style. it functions well enough most of the time but it's easy to loose track of the enemy's bullets when things start to get chaotic. the style breaks slightly when the background is any lighter shade then black, it becomes much harder to tell objects apart from the background.
Audio: the music and sounds where very functional and appropriate to the graphics and gameplay. i only noticed a single action theme and a single boss theme. some more variety would have helped out, but not major complaints otherwise
Theme: you say the game is based off of the first nadine's fleet but the two games are nearly identical. i was hoping for a more serious remix then just having a few new powerups
