Assuming that this beta has blocking of progression, and not lack of features (meaning that this beta prevents on going futher in the history, and not limiting the options like not being able to save because the gameplay is short), here is my feedback (of opinion of mine):
1- i've seen people complaning this is a copy of the map from Summertime Saga: actually i don't blame him for that since it's his first game, since i believe he is doing his own code and drawing and not taking all from AI.
2- the art is nice, lots of thicy women
3- i think the very first of his sister with her friend was pretty "rushed", like its the very beggining of the game, and we already have a scene. in my opinion, a scene with her masturbating herself with on t-shirt on would be better.
4- i Believe that there will be scenes only with the 3 characters, so in assuming that, don't the "scenes" too much, like, day 1 do this stuff and day 2 do this stuff and sexscene already. make it like when we helped sister on swiming: it took like 2 to 3 days until something happens. i dont know how's the developping plan, but just don't give all scenes that fast and keep it going.
5- about the phone: it would be cool if we could just leave the phone by clicking on it's symboll, or clicking off it in the main screen. thats because once you are in the lust legion app, you *must* leave the app and then leave the phone. or, at least increase the size of the hitbox of the "back" bottom. to me the it was very buggy to hit it beacause it was very small.
6- about the "animations": it's a prefereence of mine: but i think i would be better, instead of "animating" the Charas in the scene when the move, a "fading" effect, like when we are switching to other rooms would be cooler
