The style is good, the music is good, some of the models like the coins(?) etc are a bit bland (maybe change them to 80's colors too and more like coins or more detail). Also maybe change the font and interface colors from yellow to teal/purple or perhaps white for more consistent theme colors (could be just my opinion though). Gameplay is solid (though I am pretty bad at it
), could perhaps use some turbo key or such besides the arrow squares (could be I am overlooking something). Some hyperspace like lines but than it neon colors would also look cool I quess. I think if you polish & expand it more you can try to put it on steam as a minigame.
