You don't actually need to rush for templates and drop literally 10 games for a jam. You Should work Consistent with one game. I use the same engine as you. but i give my best. No worries if you lose or win this jam. Game jams are just a way of expressing your skills. I ain't saying that your game isn't good. I had fun playing it. But this is not the correct way to win a jam. Anyways keep in mind from the next time. Build something that Impresses the whole jam. Keep it up !
