Touhou lore :D
I think it could have a visual indicator of how many lives I have left. I also found it a bit difficult to understand if I've already been hit or if I'm about to be hit, because the collision distance to take a hit is much smaller than the plane's sprite. Aside from that, it's a GREAT entry, in fact, I think it's one of the best.
(Except for mine, of course, because there are no crows involved lol)
