As the title says, this is an extremely difficult game. As someone who had finished the story of the 1st Vaporum game 20+ times on brutal difficulty without watching any walkthrough / playthroughs, and without reading any guides on how to play the game I can tell you first-hand that this prequel to the first Vaporum game is ultra difficult. Just take my word for it, seriously! I mean, at almost every floor of the game I had to watch youtubers play the game to see how they solved some of the - story-related mind you - puzzles to progress into the story. Don't get me wrong, puzzles in a game like Vaporum are an absolute must and the more, and the harder, the better, but dear god! Some of them are just brutal. You have to be very clever to solve them, and cleverness is not enough, either. You also need to plan things well and also to really study your surroundings well. Some of the puzzles spread over more than one level, too, and on top of that you also need to remember clues and patterns, too. And I'm not even mentioning the secrets which, after thoroughly inspecting every inch of every floor TWICE start to finish I was still able to find only 1/3rd of those secrets. By the end of floor 4 I should have discovered 11 secrets in total but I only found 4. So, yeah... Anyway, overall the game is pretty good, despite of the intense focus on puzzle solving to the detriment of combat. You will get many more hours of gameplay than in the first Vaporum, but that's because of the puzzles rather than the combat which is pretty rare and easy in general. I mean, if you can square dance properly and can use your brain instead of your muscles most of the enemy won't even touch you, even on brutal difficulty like I played.
