This is a 2 day game jam. So I won't sleep, ngl just put 100% into your game, forget water, food, and sleep exist. its just you and your pc. Your welcome lol.
Even for short jams it is very important to get good rest. Being exhausted is when mistakes can pile up fast. Putting in effort is great, but taking care of your needs helps you make a better game in the end - even if it is just a 2-day jam.
