It was good. very good. and these are my tips.
find the secret room:meet sleepy aqua. and find blue curtain. and jump.
find Poyoyo : Go to Miteiru room. and Find blue cobblestone(right side).
Playable character:kill Noel as Aqua skill
Defeat Aqua:kill Aqua as Marine skill
Good ending:kill Miko as Noel
Find Miko:Be focus to it's wind. Run in the opposite direction of the wind getting rid of all the mobs.
And Ayame, Miko was very exciting. Ayame's attack pattern is various so I love ayame. Miko also make me angry which makes me be focus to game. Sui-chan's stella stella and gold axe was interesting but It was not exciting rather than two members.
and I found a little bug. In 2nd stage, when I jump forward and go inside, All reseted
and When I played as Noel, There was no Aqua in 3rd stage. (Not sleepy Aqua) All candles were lighted up. Is it bug too?
