Thanks for giving it a go! The amount of content in the second half of the game is definitely lacking, so I agree that it does get a bit repetitive. There's a progress bar that shows how far you are from the next gate, but nothing indicates how many gates there are total. I'll add that in!
I appreciate the feedback about the knight. That class is the only one who gets a summon, I'll need to look into balancing it if it proves to be *too* good. Was it easy because you had endless meat shields?
