I think you might like Palace of the Dead then once it comes out.
So far sounds like it will be the 'each room harder than the previous', since it gets more difficult the further down you get without much RNG involved.
Just see the Aquapolis as a 'Bonus' or even 'Critical Hit' for Treasure Hunting.
You already get the reward from the treasure hunt chest guaranteed.
But maybe you get a Bonus now! Crit! Portal appeared!
And now you're guaranteed the loot from the first room.
Got another Bonus, picked the right Door!
etc~
Don't think of it as things you didn't get, but rather things that are a bonus -if- you get them.
