Pictured are the cursors from Pixel Dungeon's Steam version. Linked at bottom are these cursors and some additional variations in .cur format for Windows.
Cursors may be the only thing that the original Pixel Dungeon by watabou still does best... I would very much love to see dynamic cursors and a system cursor toggle for Shattered PD. Are there any PD forks I'm unaware of that have such a thing?
For a personal fork of Shattered PD, only a single line of code must be commented out to disable the custom cursor. I have done so, and set my system cursors to those linked below.

You're correct that pixels don't always align perfectly, but this is almost always result of visual or gameplay compromise, and the general intent of the game looking blocky or pixellated is preserved. In general there are only two persistent pixel zoom levels as well: the UI camera and the game camera. IMO the vanilla cursor sticks out like a sore thumb as the only asset that's at full resolution. The Shattered cursor mimics the UI zoom, using the same pixel size as the interface. While it is obviously a lot smaller, the Shattered cursor also uses the exact same three colors as the vanilla one, I literally made it by shrinking the vanilla cursor.
