Some sage advice...
Hey folks! I'm happy to say I'm joining this jam, making it my second Ludum Dare attempt and first time doing so working with Unity.
I figured I'd pass along some tips that even I forget sometimes:
Take breaks. Even if it's just walking back and forth from the kitchen to get a beverage (see next tip), giving your eyes a rest and stretching will do dramatically improve your productivity!
Keep hydrated and nourished! Whatever your beverage or snack of choice may be, make sure you have enough to enjoy during the event. :)
Sleep is a friend that you might hate in the moment, but you'll thank yourself for getting some of it later.
KISS. It's better to be able to add features later than to start with loads of "key components" and have them all be only half-functional or buggy.
This kinda goes with number 1,but get some fresh air! It does wonders for the brain.
Cliché though this may be, I'm still gonna say it: Have fun! You're doing what many others wouldn't even attempt, which makes you pretty awesome.
Good luck out there and happy jamming!
