I've been playing 0.52 and I gotta say that the engine came a long way, I probably complained about it 3 to 5 times in this thread before about how janky it was, it got better with the new based unity engine, but now it feels better optimized, it has all the functions you want in a VN, and I love the new replay function, it's perfect, for it to be better only if you had pictures of the scenes, but it's not a big deal. If I could suggest a little something, it would be a progress bar for the videos (out of the way, obviously), so we know how long it goes, there was a video that goes for so long repeating that I thought something wrong happened
haven't played for too long, I'm only at day three, so I'll wait for new version to keep going
