Nice game concept with some nostalgic vibes. Sometimes feels unnecessary hard, like, player probably wont make it through second night if he don't upgrade gun; also it's barely enough battery to go to the depths and back, and player feels too slow. Also, would be good to have possibility to reload manually. Nevertheless I completed it after third try. Interesting concept, I bet with some finetuning, new cool upgrades like for battery and walking speed and new adventures it can be good game.
