I like the simple concept. I had fun in endless mode but could only get to tier 8.
It was really nervewracking praying for a good roll in the later tiers where you only got 1 or 2 dice from a reroll. I love a good gamble.
I was also wondering if I was doing something wrong. I noticed once I got to tier 8, even though I would complete at least one half, It would only mark it as 1/9th completed.
