first off the controls aren't listed on the about page, I think you've submitted a premature build as it does not contain the ability to pick anything up, all other features work such as the hue slider, the pause button and the health system [it has no death animation and just goes into minus numbers but this isn't a big deal] the only implemented system I would truly criticise however is the jump seems a little delayed, other then that decent job.  

I really like this, like the little cube spawner and everything else, the only thing that I would say to improve is that your pause wasn't working. Otherwise, really god.
