Kinda like what was said above. The game is pretty text heavy as it goes through scenarios from the anime/manga series. Some of it new material but not much. When it's not throwing text at you, you're playing in a mario party like style. Rolling a dice to move a certain amount of spaces forward. Each panel does something different and I'm not gonna go listing everything. Some panels allow you to play mini games but the harder levels of mini games are ridiculously impossible.
As I mentioned, you'd really need to be a Hidamari Sketch fan to get the most out of it
