Well, I was frustrated that I have no impact on what's going on and I cannot chose girl which I want to have relation with. There were no meaningful choices.
Forced romances and sexual encounters are a big problem in a lot of these adult VNs. Way too many force sex with random characters, or characters you don't like, on you. In Acting Lessons, no matter what you do that one girl is always your girlfriend. Your character will always fall in love with her regardless. Probably its biggest flaw, tbh.
If your story has no room for choices, then don't give the player the illusion of choice, it just pisses them off.
