So even though there's not much here at the moment, I really like the game and where it looks like it's going!
As far as balancing issues go, I have two thoughts:
First, concerning the energy consumption. I think that having fitness decrease the energy cost of activities instead of increasing your max energy might be a better way to go - I got my max energy around 200, but sleep only gives 70 max, and the shower only gives 25, so you can't even store 200 energy unless you shower, eat, go to bed, and then do that again, leaving you doing nothing except possibly shopping for 2 days out of the week. If fitness instead reduced the amount of energy each task required (down to a minimum of some sort), then that would be one fix. The other thing would be to have sleep (when hunger > 0) restore
70% of energy instead of a flat 70 energy, and same with showering (25% instead of a flat 25).
My second thought is this: if we are a handy man, and we are increasing our repair skill/knowledge, shouldn't that also reduce the cost of our repairs for the apartment? If we are getting better/more efficient/etc. at repairing things, then it would make sense to me that the total cost of repairs should go down as well.
Anyway, as I said I'm enjoying the game so far and look forward to where it's going! (And also to the movie files being fixed for firefox as others have mentioned).
And lastly, here's hoping for some kind of harem/pregnant harem ending!
