I will be honest with you. My brain got toasted after try to solve as quickly as possible and I gave up. Actually, I started to play it in reverse and see how much negative score I can get in 1 minute (I got -16). I admit that even the tutorial showed me how stupid I am since I had to try multiple times on simple puzzles to proceed. Still, however I played it, it was fun, but I need to clean my brain and build up some IQ before coming back.
