That’s why I don’t replay it. It takes too long if you fail. Every time I tried I either fell off the platform or got killed by the radiation bursts. I didn’t find the crystal charging piece that problematic. I’m just not willing to spend another 30 minutes when I know there’s a 99.99% chance I’m just going to die again.
If there was a save point right before the fight with Anathema I’d keep trying, but until that occurs (which I’d give a near zero % chance at this point) I’m not going to try it again.
