I'm kinda liking it so far, but... really, the first boss is absurd! She keeps stacking this one Debuff and then crushing me! You Really need to add a way to clear that somehow because 20 stacks of it is just mean. Plus, I haven't a dang clue what the status effects even do or are called. Is there a primer in the game, or did you just leave any explanation out?
Glad you're enjoying the game so far!
The boss will cause debuffs for each part of Hanaja that is in the Magical TF. It helps to go into the fight as a full demon (her default form) and try to keep her from transforming.
As for status effects, there are hover-over tool tips! Just hover over the icons above an enemy or hover over Hanaja's health bar to see what they are and what the effects are.
