Hey, I'm glad you liked it!
1. Yes, I made the talking sounds by myself ( one of them is actually my girlfriend's voice :D ), and I pitched them up so they sound squeaky
2. There are 3 endings:
a) one where you shoot the flare gun ( that you have to find exploring ) and the next day you basically won because people came to rescue. ( "You escaped" ending )
b) you go insane when you lose all your sanity, everything changes color and the next day (after you sleep) you basically go crazy in the woods ( It's the "gone crazy" ending ) .
c) you die of health and when you return from the activity where you lost your health, you start walking really slow until you can't move at all and eventually die (it takes like 5 seconds to lose all your movement speed) and you have the "You died" ending.
