Soulslike and Touhou? Strange combination, but it fits.
A challenging and interesting game. I really like how the latter bosses' attacks encourage you to use and switch between the 4 different weapons well. For example, one of the attacks Yuyuko's third/final phases has her rush you super hard with close-range fans, and if you try to stubbornly speedkill her with the spear you're more likely to either die or not have enough health to outlast her far-range attacks with the clusters of aimed fans and laser waves.
The main complaint I have is that the controls can feel kind of... slow? Especially the dodge button, there's a littleee bit of delay between when you press it and when Sumi rolls to dodge which can make perfect dodges very difficult on denser patterns. Also, the Jump button is a bit useless.
I really like the overall presentation, funny intro cutscenes, FUMOS, music is a bit repetitive but it's got that Epic Orchestra vibes to it.
Good work on the game!
