Attempt 1- lots of random wandering, falling through hidden pitfalls until I got stuck.
Attempt 2- Time to play smart, I learned what the hidden pitfalls looked like and was easily able to navigate this treacherous labyrinth without dropping down any floors. So I wander around the starting floor for about 20 minutes when I noticed that the map changes despite taking the same route between 2 points. Another 10 or so minutes of wandering and I find out that the keys do nothing, you can find a locked door pick up a nearby key try again but the door remains locked. "I'm onto you buddy, rearranging mazes and useless keys, it's all designed to throw the player off, but I'm not gonna fall for your tricks so easily, I will complete this game". Aaaaand cue 30 minutes of wandering around finding all ladders either blocked by pitfalls or unopenable gates. I don't know if this is just difficult to complete and involves getting lucky and finding the correct ladder or if you are trying to screw people over with a game that can't be beat. If it's the former than shame on you, if it's the latter than I guess you accomplished your goal spectacularly, because determined and driven by some deranged completionist compulsion I may be, but a winner I am not.
