I want to thank you for taking your time to play this game and I'm glad you liked the overall ambience of the game.
I playtested my game on my machine and it works fine. My specs were i5 12th gen, gtx 1050. The post processing of this game was optimized using FXAA antialiasing. I think I have to optimize the post processing for smoother frame rates on low end devies as well. Thank you for highlighting this issue! I will work on it as soon as possible.
