I was happy to give this a play, found a fair amount of bugs but for a demo I was pleased so far, look forward to the finished product. Don't forget Gamejolt too ;)
I did try that but nothing happened. My controls for movement also sometimes froze and on occasion they would invert which was odd. Towards the end during my summery I could continue to get a score, I think things were hitting me in the background. A few others too but I wait for the next version.
