I really like the art and audio that you have used in the game.The idea used is also good, trying to show a post nuclear world where one has to travel for resources with specialised equipment. The walking part could have been reduced a little or maybe a minimap could have been added so that player can actually have a broader view of this map. Another thing to add is that that i found it difficult the first time to actually find the safest path to the store ,i.e the path determination on basis of change in radioactive levels was a bit tricky to understand, so maybe you could improve that part a bit.
Keep it Up Mate !
