So I absolutely, shamelessly love this even if I'm too bad at the game to actually complete it (checkpointing is generous, I'm just bad at moukou; the game felt fair despite my own incompetence).
Only real criticism is the shot/charged shot mechanic; it means bullet spam requires rapidly tapping the A button and it is hell on your thumb. If holding A just spammed bullets and the charged shot was on a different button.
Loved all the little details like the parallax backgrounds and the wave when you fly low to the water. So many unique fairies...
