Is the payoff worth playing the completely fucking boring gameplay?
Nope, it most certainly is not, i've suffered through this game at least 5 times throughout these last 2 years hoping that at least the ending(s) will be good, but oh boy was i wrong.
Trying to stay as Spoiler free as possible:
You can only romance 1 girl at a time and based off of how you played you can get 3 different endings for each of the 4 girls, there is the good ending, the bad ending, and the not AS bad but still a bad ending, meaning that there are 12 different endings with the girls, plus there is another one where the protagonist decides not to romance anyone, so altogether there are 13 endings in total, which in itself sounds great, the problem is that there is absolutely nothing sexual in any of those endings. NOTHING.
By the time you reach the end of the game none of the girls are neutral, they are either in a relationship with you, or they're corrupted by the squirrel, but since you can only romance 1 girl at a time, the squirrel's gonna end up with 3 girls every single time and the worst thing is, we don't even see what happens to them during the endings, we only see the fate of that one girl who's in a relationship with the MC in all of the 12 endings.
Oh and the cherry on top is that every single ending is the same for every single girl with some very minor variation, all 4 good endings are 80% the same, all 4 bad endings are 80% the same, basically once you saw all 3 endings for one girl, you've seen all 12 endings.
