Thanks a lot for reading it!
There is indeed a sequel planned, yes. I can't talk much about it though. I'm still working on the second part. I will release the second half of the game in the next big update!
Also yes sorry about the game lagging, it's me pushing renpy into it's limits, making it do something it's not really supposed to do. I will try to improve on that but it's a bit hard considering it really seems to be an engine problem mixed with some hard to change choices now that i'm that far into development ^^'
