When I try go through a portal, to which the other side is crammed in a corner, I keep falling back to the side I have come from, regardless of how I try it. This is particularly annoying on Hell, level 20 - it takes up to a couple of minutes to go through a single portal, and there is few of them on that map.
It looks like the portals are opening back too soon or something like that, I haven't seen anybody else on youtube with a similar problem. See the link below for a video of it, but it makes this particular level unplayable for me.http://www.youtube.com/watch?v=1Fe-5RLLQ5o
Sorry for the poor quality, I didn't want to look up the way to change the framerate of the video. But don't be fooled, the game runs very well on my computer - it isn't a performance issue.
Any solutions? Or where do I report a bug? ;)
I am running the Humble Indie Bundle version on my Debian x64 Linux, with an nVidia GTS 450 card.
