It's definitely time to go pet my rabbits again. I'll be back when I have more staircases - I keep placing new ones instead of descending, so I'm going to need extra to actually get to floor 100. A lot extra. Maybe 150 should do it.
This. This right here and totally this.
I don't know what system you play on, but even with the relative precision of a KB & Mouse on PC, I still misplace at least 10% of my staircases. I would probably be a wreck on Mobile though I think I've done it on a Switch and yes, I took ~150 Stairs.
Just keep your Food source ready for the inevitable Triple-Rock block in accompanied by 3 Flying Serpents, so you can pound that rock, eat an IridiCheez, and bang down that staircase. Which of course ends up in the diagonal space you can't reach.
You
know those Serpents contracted out with the Rock Crabs to craft that nice Fire Ring around the ladder, expecting you as the guest of honor centerpiece/tasty meal for their Barbecue and Luau.
As the Serpents lazily chomp bites out of your tasty flesh, you down more magic IridiCheez shoulder rebuilder, bang down the Stairs in the actually right place and somehow make it down.
To get roasted by a pair of Dinos looking for a yummy Umami Farmer steak.
