Strangely, when I finished the last level, I got the same feeling from that that I get from beating a boss from any game that seems to kick my ass over and over again, yet the only level I had to do more than once was the 9th one. To me this was an interesting combination of 3D thinking and Sudoku, nicely done.
I'm not sure how this happened, but it happened around when I was buying some research items in the game and know no matter what I do my total blops is always -1 or it resets to -1 when I try to buy something inside a level
Each a version of Cursed Treasure comes out, it becomes a new addiction for me, nice inclusion of night levels and badges that add XP, I think when I get to the grinding part of this game, it won't feel like grinding
