It's alright, sometimes I forget what it's like to have less free time, I've been a student for three years but when I work full time over the summer it kills my motivation as well.

Looking forward to seeing what you come up with. If possible could you be pretty specific with time passing? The amount of rock John gathers is based off time, and although it's mostly just fluff anyway as the damage is balanced by T1 it helps me visualise what I'm working with if I know how much mass he's had time to gather.
