I had a liiittllle bid of trouble, but that is just me not knowing how to play puzzle games (oops). Overall I think the game was fun tho. Getting to reveal the secrets of caves and such is really cool! Even though I definetely didn't get to experience the whole game, the first part speaks for it self.
As I said, overall I think the game was very solid, puzzles aren't my cup of tea but I set my mind as a puzzle gamer, tried my hardest to figure it out and found it both challenging and fun.
(This might be rerated as the new build is coming out in a few minutes)
