Just click the flag and check your fps the browser page will most likely crash around 15-19 because if its on 15 its actually on zero because the game components make near 15 fps of lag.
L activates Huge lag spike(very likely to crash your tab, and k activates big lag spike (very likely to freeze the game), and p will ask are you sure and then if you say "yes" or "Yes" It will start a lot of lag most likely crashing your browser. Thanks to #ColbyCookieJar for the lag codes game: The True Crash Machine. Link: https://scratch.mit.edu/projects/483100267/
