So, I have now played this at work, and it is definately my keyboard at home that is causing the stuck controlls. I do agree that the platform could move a bit faster. Made it to Level 7, which is a personal best.
Is anyone else having issues with the controls not responding or gettiing stuck? I have seen this with other games here, and I don't know if it's just me, or what? Never had this issue before I uploaded it...
