It was intended. That's the point of the game where you have access to most of the upgrades and it's kind of wrapping up at that point, so maybe it is a bit of a wall, but there isn't really anything on the other side. What I was hoping was that people would like to grind a bit more to get strong enough to do the ending. Some of the complaints about my previous game was that it was too slow at the start and too fast at the end. It might have worked better if I had made it more clear how many total rooms there are since it is more discouraging to people who think they are still in the middle of the game.
