A teaser site with nothing but this image has gone up and is trying to get your attention.
Cave is known pretty much entirely for shoot ’em up games and are probably the main authority when it comes to that genre, so you might be thinking “well then this is about another shmup, right?”. In this case you just might be wrong though, as Instant Brain is supposed to come out this year, which is apparently going to be a visual novel-styled game. And using this amazing super power I like to call “logic”, which I gained in kindergarten, I found out that this year is nearing its end, meaning this teaser might be partaining that very visual novel game.
I’m amazing, I know.
