Uta to Mori no Yōkai Yashiki
Description
When a boy named Umi discovers a ghost mansion in the forest, he decides to show his friend Uta. Upon entering the two become separated, and now Uta must brave the mansion's ghosts while trying to find him again...
This tower defence game is a fusion of genres; Uta stays in the centre of a room while the player sets up things around her to defend her. It also incorporates elements of match-three puzzle games and some light action elements.
