Didn't try this for the longest of times due to its name -- "waifu academy" is a pretty fking lame name. Surprisingly though, this is actually pretty good and has quite a lot of content.
The only arguably negatives I can thing of, is that the game is very linear and while there are quite a few choices, most of them are superfluous or are straight up game-over choices. So overall I'd say the writing, story and characters are good, but the game mechanics are mediocre at best and plain bad at worst. Though I keep reading the next version will actually do something with the Karma points, so lets hope that changes in the future.
I'd however still be all for the devs removing all the superfluous choices. Why for example does it keep giving me the option to go to the store, the bathroom or the dining room, if I can't do anything there anyway? It's just so often that there isn't actually a choices -- two of the three options most of the time simply don't do anything. And even IF there actually are multiple choices you can make, often you can simply select the other choices after you're finished with the first. Now, I'm also not the biggest fan of time management in games like these, but the current implementation of the choices is just weird.
