This one's a somewhat Yume Nikki-like adventure game that was translated recently. Like Yume Nikki, it's rather surreal and non-linear, and the protagonist has different abilities that can be used to interact with various characters, much like the effects in Yume Nikki. The similarities definitely aren't coincidence either, since Yume Nikki was listed as an inspiration in the game's credits. As for some ways it differs, it's very humor-focused, and has more of a story, along with a good deal of dialogue. The story itself isn't that deep though, so the focus really feels more on exploring the areas and being entertained by the many odd things that happen along the way.
I actually wasn't expecting too much from this game at first, but it became one of my favorites after playing it, so I'd recommend this one pretty highly.
