although the game runs fine on PC it really struggles on my laptop. 16GB / 8 GB respectively. on PC the game sucks 4373 MB, on laptop it caps at 3700~ish MB, because of system and browser consumption. I advise you work on that.
after each day the game froze, went black and I had to wait 15 or so seconds. if I clicked or alt tabbed, windows notified me about the game not responding, sometimes even saying the process is frozen. I've never had that kind of performance issue with any hgame before. 4GB RAM for a work in progress is a lot
