A fun game, but controls are inconvinient. Make jump with Up arrow (better make movement with WASD) and attack with Space. U have not mention that X also closes the inventory. When inventory is opened, music stops. I got 1 level, but have not got the medal. In the level, where flying stones (or robots) appear, there is a place where the caracter half falls like in the hole. When I tryed to move after that space my browser hanged up.
