Alright, I am finding it nigh impossible to beat this game on Heavy Blizzard. I have gotten close but eventually, the food consumption is just too much. Played it what has to be close to ten times now, lol.
Haha, yeah, it's not easy! As far as I know only about 3 or 4 people have managed to beat it, and it requires quite some luck. Getting an early Biodome with lots of deer (no hunters), a Sun Lamp + Corn field, and/or a lucky temple at level 6 seem to be the main routes to surviving Heavy Blizzard.
