Aeternum - Story Mode - Lunatic ALL Clear 72 Million
40Aeternum is a very good Western-made shmup presented by WastedBrilliance.
The survival in this game and story mode in general works a bit differently from the basic shmup formula. You collect power to power up your shot, using a bomb takes up 50 power and dying makes you lose 75% of your power. If you get hit while at 0 power it's game over. Collecting enough point items gives you a panic which essentially is a free autobomb without power loss, you start off with 0 on Lunatic Mode.
You pretty much want to never die in this game as it can cripple you so severely that you're likely to snowball into a game over.
Pretty much how the scoring works is you grab power items until you're maxed on power after which all the power items turn into point items. POC for max value and graze to increase their max value. And of course capture spellcards, you capture them so long as you don't die.
This was a pretty silly run with some very silly mistakes but I can guess you can still call this a no-miss clear.
Mostly used safety strats for this run as I really didn't want to die. You can reliably use a bomb on every pattern as you get the power for it back after the attack ends, so use this to your advantage.
Apart from Story Mode the game also has an Arcade Mode, Pacifist Mode and Arrange Mode as well as an Extra Stage and different playable character.
