sure, the point of game jams are to have fun and learn from our mistakes, if we do something which is not meant to be done, we wont do it again in the next jam. if we forget to submit, we wont forget to do it next time. this is the point of game jams, sure it might be pressurizing to complete the game in such a small amount of time, but if you complete it and finish the game and managed to submit it, then you can also improve it and stuff like that. you will get feedbacks from other people too and most of them would be honest feedbacks !
heres mine if you wanna play :D
