Thank you for this game and having a way to go over the puzzles for people who are not very good at it, including me.
Also, if you're going for a multiple ending game next, I suggest to use only decisions and not for the puzzles solved. And you might want to add a skip or a recommendation or a hint to save before making a decision to change the ending.
Speaking of saves, you might need a lot of slots for that if you're going multi ending. You might need a skip button for this, too.
The search option for the Nursery part has made Juni, obscured on it. I ended up clicking on the white circles and missed a piece of the puzzle. If the circles were meant to be helpful, I would like to recommend to remap the circles on Juni's area because the 2 circles near Juni always points out to Aceru. I hope you would be able to fix this or if it's just my game.
oh wait I found it.. LOL there was another door.. so a sequel would do. It looks like this game was meant to advertise other games. So it's fine if it's cliffhanged and too short.
