well, i hope you are all correct regarding this game dev and its developing speed.
i cant say i took into consideration his days off, just an overall "feeling" that he is slowing down compared to previous releases, while he did hope the development should become faster considering his (now) improved hardware.
at the end, it seems as for now he is more or less on his average speed, at least for the last few updates.
and i wouldnt point out "improved graphic" as a positive argument regarding dev.cycles, or we might enter so called "oceans 9 circles of (developing) hell"
