I did some work on this game for RTA purposes and have some useful tools and information to share.
First off, this is a fantastic little adventure game much in the zelda style. Quick dungeons, a central world, and quite a few optional collectables. I routed out 100%, but any% should have some interesting pieces to it as well.
I have a lot more technical details available in my notes, but for now keep this in mind:
-Perfect horizontal/vertical movement for each character is given in terms of value + subpixel values. Mouse is fastest, moving exactly double the rate of a walking human. Moving in diagonal will move you at approximately .7x your normal rate in both directions.
-Zips exist, although currently are only useful in a couple locations. The hitbox checking has bugs specifically for the Mouse that let you slightly clip into seams in some tilesets. The main use comes from moving the iron balls with the magnetism from either underneath or right, and then using turtle to complete the clip into a wall. Turtle is best because the clipping operates on sup-pixel positioning for continuing zips.
-For any%, some skips are possible, but unfortunately there are some hard story triggers that prevent skips. For example, there is a barrier in Turtle Altar until you pick up the Lamp. It would be possible to progress through the Altar without the Lamp, but it doesn't even let you experiment with that.
-Lots and lots of quick kills are available for bosses. I found a number of setups in my run that are pretty close to optimal, but I'm sure some can be improved further in a TAS setting.

I will post my hitbox viewer script later when I get access to it again.
