Lost In Blue 2 Cheats (Nintendo DS)

You can only go to sleep if you do not have 0% for water and food. However, that only
applies to your character. The game will still allow you and your partner to go to sleep
if you have at least 1% food and water, even if your partner is at 0%. You can both rest
to fill up the stamina meter as long as the character you are playing as has food/water.
Hold the partner's hand to rest.

Successfully complete the game in Regular Survival mode to unlock Serious Survival mode.
In this mode, you must survive as long as possible without a partner.

Go far into the jungle to find a grassy place where you can make another house.

You can ask your partner for food and firewood. When you have 40% or less, tell her or him
to get food or firewood.
