Finally bought this marvelous game. So. Fucking. Hard. This is gonna take ages for me to beat and even then I'll be mediocre at it. I bought it this morning and finished the first run and gun level along with 2 bosses of the first area. 13% completion.
I recommend it fully. Wonderfully authentic, great score, fantastic originality and challenging (sometimes too challenging). I do wish they would've had a more casual difficulty choice because failing over and over and over after awhile isn't fun. When I'm in the same boss phase 30 attempts later it lost its charm.
