Yeah... doing all that I did in one day was very rewarding (I have one hell of a character controller now and learned a lot of coding to get my project together) but I ended up exhausting myself on day 1. I went from 5pm(ish) to 3am on day 1 and then when I woke up I worked without eating until like 3pm again. I wanted to do days 1 and 2 just as a first time test but I only had the energy for one.
I've never felt like an old man in my life before. xD
