I found this quite... Interesting, it reminds me of those weird horror games in wich the psychedelic part gives it all that eerie tone.
As an art piece, it's interesting and psychedelic, although it's not my thing. As a game? Well, it barely has any gameplay,
I would rate it quite.. Meh, mostly because i couldn't understand the point of most of what was happening, i guess reading the japanese phrases could give some more context to it all, but sadly i lack any knowledge of japanese. I do like the psychedelic, "acid trip" style of it.
