I see, how strange. But great to hear that you found a way around it! Now that i know that this switch made the problem for you I also can look into it and see if there might be a bug.
And thanks, very glad to hear that you had fun with my game : )
Eternal Dark is supposed to be active there. As you can see, even without upgrades you would a have a sight radius of 50 pixel. And with upgrades and certain tf's even more. It might realy be a emulation bug in the end.
maybe could also be my phone as I didn't think about that might be a combination but that's ok I was able to enjoy your game and that was what matters to me keep up the good work but remember to take time for yourself as well dont make yourself stressed depressed or burnt out
