I've tried the demo a little bit now. It's good to see ZUN kept Spell Practice in, I really like the stage 3 boss, she has some fun attacks, I think I only managed to capture one on Lunatic though they were pretty hard >.<.
Did a run on easy to see how many resources you can get
can't say anything for the scoring system all I can see at the moment is graze to increase PIV, hopefully there's a bit more to it than that.
Overall it's been a fun game so far

That was a full bomb stock +1, getting an extra bomb with a full stock already doesn't loose it, after using one your stock is still full.
