spining was the most wacky thing I've done so far, very nice pov, I really like to feel like a plane xD.
Reimu isn't that nice, she just float away and is confusing at most, camera doesn't follow her at all xD.
A little bug is that if you start at the shrine and retry, the next mission is the SDM, quite weird.
Overall, its quite good, probably some collision is missing specially with buildings, but still quite good.
