Very interesting concept! The ambiance was really good, I enjoyed the idea and the gameplay, the graphics were fitting and the animations were smooth. It is well polished avec very enjoyable to play, well done!
The talkie-walkie was a bit OP because I just had to ask for supplies before using my "charge" cards, and I never had to bother about food and water again... Maybe limiting the talkie-walkie to once per day would be more interesting ^^?
Very solid entry, congratulations!
