If the main protagonist dies in game and stage is restarted, objects such as Keys, Potions and Ammunition may not respawn. See solution below. (Not sure whether this happens on android device.)
Solution: Delete the "WQM.map" found in the assets folder. DO NOT delete "D3DX9_39.dll" as it's the game savedata. See Picture 2.
exit game go to ux0:data/gms/[ zombie mine ]/assets/WQM.map <-- delete this
