Give us feedback please

I've put many hundreds of hours into this game, and I'm probably done with it for one reason: Lack of feedback. I love almost everything about this game, but I can no longer tolerate the fact that I usually can't determine why I died. If you can't figure out how to add some kind of log or replay, you need to stop adding boss modifiers which can instantly kill people. Period. Full stop. That's it. Fix it.
