So I was playing this for the Christmas jam, and here are my thoughts:
The jumping puzzles are WAY too sensitive. Because RPGMaker has you move right first when you hit the right arrow, to jump to the right (or left) when coming off a ladder I had to hit the arrow key then hit jump before I fell. Which I often didn't do in time as the window was too small.
I'd encourage either another engine or at least one spare tile between the ladder and the edge, or a plugin to have you turn first then move to fix this, as that small window made this really hard for me to play.
