This was hard enough that I think I only beat one pattern. That said, this was super cool and the trickiness of it was fun to control. Big fan of how games like this have used aspects of Flappy Bird design this jam and the lil' bird sprites are very friend-shaped.

Really fun. I never really got used to the movement but was able to beat the first spell on easy and the rest on normal. Mystia's 2nd spell card was by far my favourite, it's a really cool combination of Mystia's blind gimick and flappy bird.

Oh goodness. The Touhou/Flappy Bird combo is hilarious and ingenious.
Patterns that would be really easy with normal movement from Touhou suddenly get hilariously hard.

I think the balance of the spells are pretty good once you get used to the main mechanic.
So, hard but fun and funny. Also I see what you did there for Mystia's 2nd Spellcard.

(From a dude who touched only Hard mode of this game)

i beated the first and the last one on hard and the others on normal

kinda frustrating (flappy bird) but neato

the sprites are cool

focus rationing is cool

yeah

Great mix between challenge and fun. Combining flappy bird with a bullet hell is really creative and super engaging. The 2nd spells for both were my favorites. 

This is so much more addicting than i thought it'd be. Surprisingly a fun game. Cleared the first spell of each on easy and the second one on each on normal. Kogasa's first spell is really hard because it's all randomness. Not much else to say about it. Her second spell though is really really fun. I figured out the best strategy to beat it is to stay all the way to the left so the bullet spread is the biggest while not having to worry about horizontal movement at all. Spent the longest on trying to beat it on normal. Mystia's first is also really hard even on easy. I like how the aimed blue shots seemingly end at your X location. Giving some benefit to constantly go closer to Mystia to bait out a shorter blue attack and back away from her for safety. Mystia's second however is my favourite spell in here. It perfectly mixes Flappy bird with touhou and is the most fun one to do since flappy bird was made in design with pillars after all.  It was also the easiest to beat on normal.

Hope you add more levels to this. There should also be some more sound effects to make the gameplay a bit more impactful. Especially a sound effect for winning (maybe slow motion before the boss dies?) as right now it's pretty anticlimactic. The boss hitbox should also be a bit higher as it's fairly difficult to stay in the middle for all your shots to land on it. But this game is really a hidden gem despite how it looks.
