HSiFS 1cc (Cirno Winter (Easy), No Sub-Season Release, No Bomb (though I might bomb in the full version)):

Stage 1:

Fairly easy.

Midboss: Just fit yourselves through the gaps that Eternity Larva's bullets form. The gap is fairly large enough for you to fit in.

Boss nonspell 1: Same mechanic as before, but watch out for those small circular blue bullets.

Boss Spell 1: Same thing, but faster-paced.

Boss nonspell 2: Same as nonspell 1, but the circular bullets are now red and move faster.

Boss Spell 2: Watch out for those zigzagging scales and ovular bullets that come down at you.

Stage 2:

The mountain hag is annoying. She starts her boss fight right after we defeat her as the midboss. Also, her bullet patterns are dense.

Midboss: Dodge those kunai coming at you (if you find any safe spot (but I hadn't found any of them in this pattern), please help yourselves into that too, in order to get extra enemy damage for your shot).

Boss nonspell 1: Same mechanic as midboss pattern.

Boss Spell 1: Dodge those projectiles, which initially spreads out in a circle but then bounces back at you, so after a while you will found it pretty dense, so be careful.

Boss nonspell 2: Same logic as the last nonspell.

Boss Spell 2: Dodge those "knife slash" projectiles, and since the period between the last slash and the next slash is fairly short so this pattern is also fairly dense, too.

Boss last Spell: Fairly easy. Just dodge those red knives, which at first move fast but become slower as it reach the bottom.

Stage 3:

It is more difficult than the last stages because of Aunn's last spell. I lost a live during that spell.

Midboss: Easy. just dodge those pink and blue bullets. Remember that if you clear the pattern before time run out, you will get a 1-up item, so it guarantees you an extra live during this stage, even though you might earn another by scoring during this stage.

Boss nonspell 1: Bullets that initially spread out, but then moves downwards to you. Streaming bullets might be handy during this nonspell, but I hadn't do it.

Boss Spell 1 (Dog Walking): Ovular bullets that initially spread outwards but then follow you, the turn red and moves away. Streaming also might be in handy.

Boss nonspell 2: Same logic as nonspell 1, but moves in a spiralling motion.

Boss Spell 2 (Komainu spin): Spiralling lasers and then fast paced bullet clusters, and then the whole thing starts over again.

Boss nonspell 3: Same thing as the last nonspell.

Boss final Spell: Fairly hard because there are two Aunns who shoot spiralling bullet clusters, and when I tried to force me through where two spirals met, I lost a live. After a short time, the second Aunn explodes and releases red ovular bullets that spread out in a circle, then Aunn will split herselves into two Aunns again the whole thing start over. Again, in my opinion, this is the most challenging spell in the demo.

That's it for this playthrough!

Hope that I will release the playthrough for Wily Beast and Weakest Creature (with me playing as Youmu) soon!
