At first, didn't know what to make of the this game, if it can really be called that but I found myself really liking what you have made. It could have been another Mario knockoff but taking it further by having the characters single death be final and the story you told after said death earned this a high vote from me.
What really pushed it past just being just good was when I tried refreshing to play again to see if I could get further. Coming back with the game over screen with the memorial and refreshing only to find a grave, and then coming back to find grass growing on that grave. Genius in my opinion.
