yeah i actually based this game off of polybius. there was cut content where i planned to have the white spinny triangle enemy act like the polybius pentagram or whatever u call it.
also i think your confused on how the scoring system works, or maybe i took what you said the wrong way.
for example if you shoot the blue symbole that contains the number "3" you would get 3000. but then if you shoot it again it would be 3300. so if you shoot the "9" symbol you get 9000 points on the spot. basically it goes to (score * 1000), (score * 100), (Score * 10) and then (Score * 1)
if your still confused let me know, sorry haha.
