I gave your game another play, but I only got the gun and I don't know what to do next. There is no information provided what objects I can interact with.
you need the heap of ash. i think it is on the lft side of the last screen in the first level. i should have made it more visible, sorry
I've edited my first comment. It was nice to play, but some highlights and better character graphics and controls would be nice.
its my adventure-kit i made in javascriptand and i will improve it
