Quick Answer
MONOMOON has no double jump and no wall climb. The movement hint in the book is the roll.
Is there a double jump or wall climb in MONOMOON?
No. You get neither a double jump nor a wall climb. Out-of-reach ledges are not waiting for a jump upgrade.
What is the movement hint in the book?
The book page points to the roll. If a spot looks out of reach even with the roll, movement is not what blocks you; look at the room's puzzle instead.
Does the roll change when you are dizzy?
Yes. Rolling is faster while you are dizzy.
Are there invisible platforms?
Yes. Some platforms are invisible, so a gap that looks empty can still be crossable.
For other items to find, see the MONOMOON upgrades and items guide. If you are stuck on a puzzle, use the MONOMOON walkthrough.
