Hello whitepaperchan,
i tested out on few systems and there doesn't seem to be any problem. It seems that the browser might not be getting enough power to run multiple gui's at once, i will perform some more checks, try out the windows version for the best experience.
try resetting cache/cookies and check if browser is not allocating enough memory.
i am glad you took time to inform about this. thank you!!
Thank you for the response.
Maybe, the browser is really the case. After restarting the game and loading autosave the error wasn't there anymore (there was one another instance after, but it looks inconsistent).
The story is very nice. And feels rewarding.
Battles are mostly easy but that's fine (especially considering game being storybased).
I like this game.
