Many thanks for playing and for the feedback! I've been trying to be mindful of the initial learning curve so I'm glad it read well.
I had those exact thoughts actually! But then I realised I hit the ceiling of my level design capabilities and the deadline was looming pretty close. I'll say I had planned a few harder levels, including one with just a lot of chests and keys and the solution was to find the correct path to equally split right number of them for each room, but it didn't work out unfortunately.
