Loved this one so much i put the time in to 1CC on OG very hard mode, one of my favorite games of all time! Probably the most known part of this game is the OST which is straight fire in FM form, but when it's blasting in sync to the ever evolving and escalating levels on your way to the moon it becomes something truly special. Very much rides the line between a traditional shmup and bullethell but with it's shield mechanic it gives a very unique feel that ends up being more about routing and proper tool use with some raw dodging skill on the side. Great selection of difficulty options for all skill levels but does take some time to unlock extra options and such depending on how much you're scoring. Training modes not being fully accessible without grinding is what i consider the games only obvious flaw so be ready to credit feed a bit starting out to learn the game for a 1CC. Highly recommend it regardless
