Review, because I have free time, and for another reason.
Player -
DSanae AStage - Pretty good. Although the parts with the waving enemies going down spouting bullets behind them could work better as a spell card than a stage pattern, but that's probably just me.
Midboss
-Nonspell 1 - Nice, it remained faithful to Miyako's original danmaku.
-Spell 1 - This was a bit too easy for an extra stage spell, even/especially for a midboss. I could easily move through the kunai and the lasers. There was no real need to move up or down.
-Spell 2 - Again, a bit too easy. Reminded me of ExKeine's 2nd Spell. But otherwise it was fun to dodge!
Boss
-Nonspell 1 - OK
-Spell 1 - The lasers can make you panic if they spawn on top of you :V. A bit more variation would've been nice, even it were just the color. But good spell nonetheless.
-Nonspell 2 - A little difficulty jump here but otherwise OK
-Spell 2 - Not too good with bullets near me that shoot bullets but it was alright
-Nonspell 3 - A bit easy
-Spell 3 - Wayyy confusing at first due to the bullets seemingly changing direction randomly. But it was easy enough to learn the pattern. Then again, really confusing.
-Nonspell 4 - OK
-Spell 4 - The red bullets were kinda useless as your movement can be timed to make them go in the direction of the previous "trap", which you already dodged
-Nonspell 5 - OK
-Spell 5 - Reminded me of Perfect Freeze. You could also make the bullets ease out of their time-stop-ness but it's alright
-Nonspell 6 - OK
-Spell 6 - The laser can be easily disregarded if you just stay where it spawned :V
-Nonspell 7 - Agh confusing bullet hitboxes hng
-Spell 7 - OK
-Nonspell 8 - see nonspell 7
-Spell 8 - Pretty curving bullets are pretty, but easy. Also i do not see the relation between the name and the pattern
-Spell 9 - Easy, and lasers are also too easy to dodge.
-Final Spell
1st Phase - OK, but the bullets are a bit too random
2nd Phase - Easier than the first, really. Also again, avoid using random bullets
3rd Phase - GIANT DIFFICULTY JUMP HOLY-- oh nevermind. Last few seconds are like Gengetu Rape Time tho
TL;DR make some spells harder. Oh and the BGM doesn't loop correctly, but that's a bit out of your control, so it's okay.
Also,
please, at least tell us where you got the boss picture. It can be insulting to the artist, whom I just happened to have a nice little chat with.
