Comparison of v0.03 to v0.04 - the only editing: trim start and finish and align mouse clicks. There is minimal difference in load time from the save. The slight delay to transition between close up of mom and walk animation is that I mistimed the synch of the mouse click by 1 frame.
That's could be as simple as more data in the save and any given number of environmental issues from a user's perspective (number of applications running in the background, etc). My system is 9 years old with no hardware updates and runs this without any game effecting lag. If you are finding noticeably different results - it may be your system.
