Same haha Suddenly I had two dice and I was like "this is too much for my brain".
I like challenges, but it was a little to much for me. I'd probably would be less overwhelmed if the multiple dice mechanic was introduced more smoothly and gently.
Absolutely, it could have done with more levels. Both of the last two are big difficulty spikes. The second die was just a way to vary the gameplay without having to make more assets.
