Glitch in sprite switching

ok when i used alanzo with code


and i made a mistake and i repeated it and the blocks was busy and in 1 second all i can see in the website is just white
here is what happened

looks to me like the tab ran out of memory.

if the tab ran out if memory, then it will clearly say a website error with the out_of_memory stop code

now that I think about it, I've seen something like that happen before. Snap doesn't completely crash. I don't know what's happening, but maybe check the console (ctrl + shift + J).

or f12?

oh, yeah, that too.

fn+f12 for you then.

or ctrl+shift+j.
