Too easy :V
Seems to me it was intended as "Touhou Lite".
Works, because some friends of mine I've been trying to get into the games but complain they're way too hard. This helped get them to try it.
Also, I've heard something like this against the stage 4 boss....atleast with the 4th shottype.
That's indeed the case, since stage 4 and its boss are related to Nightmare City (which is best-known for that song... and Southern Cross, but Northern Lights is clearly more epic).
FUN FACT: The other stage 4 boss has the Icicle Fall -Easy- trick for his first 3 attacks, even on the hardest difficulty. And his 4th attack has an equally easy blindspot. And his last two nonspells are clearly Perfect Freeze. Clearly this guy is a total circle-nine.
And possibly the strongest.And lol at the characters. :V
All the bosses and playable characters are Japanese flash artists. I feel so nerdy that I was able to recognize half right away...
