Wow, you just blazed through the entire thing in one sitting! The amount of struggle you had with Game Over and The Big Picture is what I expect a blind player to go through with EVERY stage, but you first-tried more than half the game! (This is the reason the score screen can't be skipped the first time you beat a stage, I figured players would appreciate a break - I guess I should change that to make them skippable from the get-go...)
GG at skipping the entire last phase of the final boss too, you had so much DPS the attack pattern didn't even have time to spawn in properly!
(Having to read mail to unlock stages is a similar intentional choice - it's used to drop the plot on you, gives hints about what's ahead so you can make a more informed equipment choice, and it's supposed to give you a break in the action... I guess I should add in an option for that too...)
And sorry for making an even more incomprehensible plot this time, a lot of stuff are references that makes no sense without knowing Touhou lore (when moving from the japanese-only PC-98 to Windows the entire universe was reset, this was later in turn made canon, and this is what the ending revolves around)
I also never realized how busted melee damage is, enemies can hear you do finishers but I guess I forgot to make them hear you oneshotting their friends right next to them... (I tested every stage with the default equipment to make sure they're beatable without upgrades, which also means I barely tested how upgrades affect the balancing)
And yes, it's the "The Shining" carpet. I stole the idea from Anger Foot.
