Damn weapon system, needs 2 slots
I Enjoyed: The pixel game art, the combat/searching/rescue mechanics, overall appearance.
You lost 4 points because of the weapons system. If I buy a weapon then I expect to be able to use that weapon. I don't want to buy a Shotgun 2 and accidentally replace it with a machine gun 1, never being able to get that shotgun back.
I would suggest two weapon slots. One slot for picked up weapons and one for purchased. Its fine that weapons overwrite each other, that adds to difficulty. But if you players are spending big game dollars on items and then loosing them for no reason thats negative reinforcement, and it made me not want to play this game anymore.
