Been playing on and off since the game came out. Having to log in so many times a day really burned me out, now I don't feel like playing anymore :(
I found it much easier to do if I stall on part 10 of the Act 2 dialogue. It allowed me to use Homer, Hawking and everyone at the polyvac to gather Chronons. Sometimes I was able to get Homer to effectively earn at a premium rate since he got 33 Chronons in 2 hours, but mostly I stuck to the 4 hour cycle.
