The + money skill is broken. I had it at level 3 when I beat the last level on normal and got 42k, beat it again at level 5 and still got 42k. I should have gotten ~60k.
Only had to look at the solution for 2 of them. It's a pain in the ass to try and rotate the pieces. Lots of the puzzles can be solved way easier that the way they were meant to be solved. 2/5
