Same experience after 8 hours. I can see how roguelite fans would enjoy the dopamine hits of new information / upgrades / solving tiny bits of puzzles. As a pure puzzle fan I found the roguelite stuff repetitive and boring, and the puzzle stuff itself is good but not mindblowingly good. (Yes - even the less obvious puzzles)

I had my doubts when people were playing 100+ hours of it. That gave me the idea it would be a skinner box type game that is addictive but empty. So far nothing has changed my opinion on that.
