* Advice for new player reading this: when you tap 'up' to grab a ladder, you will let go and fall on the next keypress, so don't try moving left or right on a ladder just jump immediately
* The grey stuff I'm supposed to avoid (the cloud, the dotted lines on some walls and floors, triangles) should be a different colour from the grey stuff I'm allowed to touch (ladders, platforms, walls, banding)
* Too often, the thing I'm supposed to jump onto or avoid is off-camera, and I can only guess and fail and memorize all the places where I failed. Twenty seconds of precision jumping just to jump into the void for another guess is not my idea of fun
* "ten minutes" maybe if you already know all the correct movements
