Hey Junijunuo, thank you for playing and for your kind words <3,
Yeah I know what you mean, right now the chat just prints everything so you can scroll up and see your first interaction, but that proves to be too much, specially for android devices, and it's going to get worse when I add more girls and stories to the mix.
What I think I'm going to do is add a system to load and un-load chats on scroll, so you see only 20 at a time or something, but that could take a little time to implement...
What I could do right now (Only while I figure the other stuff) is add a button on settings to just disable past chats, that way you can reload the game if it's getting too slow
Thank you for the feedback! I'll work hard so you can enjoy the game lag free
