I did not know how laggy this game was on different laptops, on my own it was handeble to have 600+ slimes, so I based the crash on that and not on 150+ slimes isn't handeble. Sad :(. But you crashed it, Nice job!
honestly if you are causing a real crash and not a "fake" designed crash, I consider that almost malicious design and would strongly urge you to change it
