Hey, I just checked your bug report and I can confirm that gravity gets stuck. We will try to fix that issue asap.

This bug should be solved now!

I can confirm that this particular issue is fixed. But I'm facing a couple of more.

1. Depression's last level:
If I pause the game and then resume, the button doesn't work. The sound of gate's opening can be heard but doesn't actually opens. As soon as I visit the pause menu and resume again the gate works fine.

And note that it doesn't matter if I use Steam Overlay, it's happening because of the Menu, I think.

2. Same Level:
If I pause and then resume, I die immediately in this position. If I'm playing the level right from starting then there seems to be no problem. And I checked this situation in different parts of the level and there seems to be no problem.

3. At the Start
I've been seeing a few bugs that game doesn't work from the start and I've experience that too. But I didn't have to restart the game but I just had to click on the screen to make it work. Like we click on a particuar window to use it, just like that.

Just tell me if you need any more information. I'd be happy to help!

1. We'll look into that.

2. I already tracked down what causes the immediate death. This should be an easy fix.

3. That is interesting. On which operating system are you playing?

Windows 10 x64
