I have entered 2 Jams and made a game and submmited it, and both were failures with issues I couldn't figure out in time,

is there a Jam to give them a second chance some how like what they was supposed to be gets reworked for the new Jam and I could try to team up with someone to achieve it, also I can't pay anyone for their contribute so if there's such a Jam and someone is interested in teaming up but I can't pay you but you wanna work somethin out to make up for that chat on Discord:  Cat Trainer Cinos#6518

Yes, there are Game Jams here on Itch where you can use old projects. You have to dig around for them sometimes, but I've seen about 2 or 3 so far. There are also Game Jams that last longer than a week to give you more time to finish.
