That's strange. I've tested this example from multiple mirrors and it works for me. I suggest downloading from another mirror if you haven't already, and possibly clearing your browser cache.
I just downloaded it and it's working fine for me too.
I like this method a lot.
I never thought to use Yprevious to check for that variable. Thanks.
This engine has a lot of potential, yet it is flawed in at least a couple of areas. For one, when standing on a jump-through platform, if you move to the right off the platform and then move back quickly, the player object will appear to float for a short amount of time. Secondly, the y-axis of the player seems to jitter quite a lot. I'm not sure what you did to cause this, but it feels very awkward.
I'm not sure if this is what you're talking about, but I just discovered that sometimes the block will slowly fall through the platforms if you don't quite make it all the way through. I'll try to fix this. If this is not what you are talking about, I'm not sure what the jittering is. It doesn't happen to me.
Edit: There's a new version.
