I had the painful experience of watching another steamer struggle with Paradox Vector today.
Extra Health
I did add some extra health packs to the game to help prevent getting stuck with very little health right at the beginning of a dungeon. However, it happened at a place I had not considered before.
Now, when you get the Paradox Triangle at the end of a dungeon, your health will also be restored fully.
Missing Shaders
Also, I had a problem getting the game's shaders to work on my Windows 8 machine. I am sure some players probably encountered this as well, though I have not heard any feedback about it.
By including an extra DLL "d3dcompiler_42.dll" I am hoping this may resolve the problem, though I have not had a chance to test that quite yet.
Did anyone else have issues loading the game's shaders?
