Hey, I like your game, played it through. First, music is retro and cool, pixel style is cool too, idea is good, had struggles in the third level get it done to move forward and with z to move the key back, I was missing something like a quick info or how to, or at least a replay level function, when the key was lost in the first attempt, so I had to restart the game. Overall a cool game, I like it, please check out Tiny Kingdom too, thank you.
