Anyone wanting to easily win the "hunting" game, and also rescue Mom before anything goes bad, can just edit two files to fix that.
1) In ./game/1hunt.rpy - find all instances (should be 10) of "timer x.x" where x.x is by default zero-point-something (0.5 - 0.7 etc), and change that to "timer 5.0" then save.
2) In ./game/script.rpy at lines 3037 and 3049, same thing, change "timer x.x" to "timer 5.5" then save.
Now you have 5 seconds to hit each animal on the hunt, and 5.5 seconds on each of the two icons when saving Mom.
