When I play this game, I can't jump, but it very obviously looks like you should be able to jump. I don't know why jumping doesn't work. Edit:Z and weirdly J are the jump buttons.

Fun little puzzle platformer. I think it would be cool if the heavy weights could kill the player if they fell ontop of you, adding different ways to kill the player. But really good stuff!

It took me a while to figure out there is a "jump" button. I could only get past level 1. I wonder if it is possible to do a reverse run of the game (i.e. going from level 8 back to 1).
