Wow... I try to give every game starring a hot, curvy milf its time of day, but Melissa's Adventures has to be one of the worst VNs I have ever played on this site.
First of all, let's address the elephant in the room: There are TONS of missing images and incomplete scenes. I know you're calling this "an Alpha", but this isn't even in that stage; this is like in the proof of concept stage.
Second, and very glaring, the dialog is absolutely terrible. It almost seems like it is either AI generated, or shoved through some sort of translator. People do not talk like this, and it takes you out of the experience immediately.
Also, what the hell is up with getting a game over, and the game immediately closes out? No main menu, or nothing, just flat out closes.
Sure, the model for Melissa is hot, but this game is littered with so many red-flags, and technical issues. I don't often say this so bluntly, stay away from this game!
