Thank you, there is still a lot of work to be done.
It seems like you are definitely on the right track and that you have a great understanding of what makes these types of games fun and engaging. I'm excited to see where you go with it.
I still never figured out what happened to the Collector but I'll probably just start over and pick different stats and what not. I need to see what happens next! :)
The collector finally spawned again after wandering back and forth for awhile. Not sure how I made it glitch but I was able to defeat it. I was stuck on the Devouring Maiden where sometimes their health would be almost nothing after fighting from inside them once but other times I would have to do that 3 or 4 times before it was damaged significantly. Then it started getting stuck and flashing against the right wall and I was able to get the last hits in during the glitch and progress. Oops.
