One one hand you have dicent renders, and the game was showing promise from the very begining.
On the other hand the imbalance of choices and excitment between male vs female routes is staggering and said promise was delivered only for female route.
As a sister you have nearly two times the sex scenes, far more choices when it comes to actions, and way more lore. Not to mention the feeling of badasery and empowerment, to the point where, if you dont like the endings presented you can choose to ride away on the bike while flipping people off.
As a brother you get two times less choices, more grinding, almoust no option to be dom and abuse your powers (as an example your sis was able to kill her former boss, send her to jail or summon rape monsters to break her. Worst you can do with the same bitch is spy on her twice as much while having horny troughts, and then decide do strip her naked, stick a knife handle up her ass and take pictures.) Also, playing as a guy, you dont get to be a proper dom and clap your sire from a position of power like your sis. Instead you have 3 unique rape scenes 2 of which are poorly executed and 100% driven by porn logic to the point where it is more laughable than fapable, and 1 scene where you are ment to ingame feel like a piece of shit. Even if you have a maxed out sadism and probably shouldnt care as a character.
All in all, the part of the game where you chose to play as a sister is 4.5 out of 5 for writing a good power fantasy where you can feel said power. The part for brother looks like some sort of lazy lineral shame fest in comparison with 2 out of 5 for effort in writing.
If the games were separate i would have barely given a 3 for male route, and 5 for female route. Since I was in this mostly for powerfantasy from male POV and that was executed poorly, compared to ther sister route, ill give it 3 stars instead of 4, and keep it that way until the quality of routes, as well as quantity of choices and sex scenes will be increased for the brother route to match the sister routes in terms of feels.
