Definitely weird puzzle games, you can get different types of ending everytime your making a choices despite there is no translate to understand but is good to play it. i recommend another game as same type like this one but despite the game writing in Japanese so is hard to search
As the name suggests, it's the fourth game of this series. I played all of them and I'm still waiting for the next game (maybe)
you know it's a good game when it's from G.Gear.inc
another simple yet interesting game, can be played casually too
