Yes, it's THAT hard. I wanted to say that I enjoyed it, but I didn't. But I didn't hate it either.
It was a very tough experience, but then again, all your games are like that. Tough.
If I would compare how does it feel to play your games, I would say that it's like having a week long constipation.
But still, there is literally nothing about this game that I can criticize, as the game is the epitome of challenging. It's not impossible, it just requires a lot of learning and trial and error.
