Hey, thank you for your great comment ! Did you play it in the HTML version or the Windows version ? If it's on the windows version we hope that the dynamic lightning aren't too heavy for less powerful computer, as we both have a good machine.
I used browser. I tried again later on (I wanted to show it to my son) and that time it worked without any issue. I assume my machine was overloaded when it crashed. My laptop is actually not a good one, fyi.
