Can you optimize the game please it's really heavy on the mobile
my mobile has 4GB Ram
I always test the game before release and I personally don't suffer from any issues.
With the recent update, it should run smoother on Android systems. A restart may be required though. The game is quite animation heavy but that shouldn't cause any lag whatsoever. Aside from that, it's a port similar to all other Renpy games on this platform.
Sadly, I don't have any proper solutions to the problem.
