Are you able to put the plate in the microwave, turn it on, then turn off the microwave when the timer is at 00:01 or 00:00? The game has a lot of lag on the web build, so that could be a hindering factor
ohhh I didn't fully realize the emphasis "right before" it beeps. I kept trying turning off the microwave at 00:01, but when I waited a little bit more I was able to open the microwave without beeping.
But now I have another problem :( Is the resaurant supposed to be this dark? I cannot see anything. Maybe I missed something again ...
