Shows hitboxes and a bunch of information. It's also our RAM Watch, but that was underutilized anyway. It has my guess on Ronald's hitbox rather than anything firmly known.
It also has my early guess on the wall hit detection, although now I realize the magic pixel is just at the feet level and not the vertical orange bars I put down. The green vertical bar was to assist in figuring out the item collection, and seems mostly accurate.
The "average speedometer" and "distance check" on the left needs to be calibrated to the start of each stage.
