I was submitting my game a minute before submissions closed. i would never see any sort of way for me to know if it submitted. Its about 30 sec after close time that I'm typing this. Im worried that it didnt submit so im sending this as a time stamp for when I tried.

Winter Jam Submitted by theBailey — 4 minutes, 33 seconds before the deadline
