Making a game in 48h is hell, but totally worth it!
I think everybody had the same anxiety at the finishing line. I submitted my game almost 3h before the finishing time because in 2020 and 2021 the itch io server crashed at the last hour of GMTK Jam.
At the time I uploaded, the jam had almost 1500 submissions. More then 5000 games was uploaded after that! It is wild!!
