played through it again, found one last bug from that edit I had you do, that makes jumping up through platforms sort of... interesting.
where I had you add
ySpeed = 0;
change it to
if (!jumping){
ySpeed = 0;
}
that just prevents it from stooping your jump momentum when you pass through a platform.
hopefully that's the last tweak.
anyway, you have quite the assortment of locations listed, but the only transformation idea that pops to mind is a penguin in the arctic even if not technically the right Reagen. maybe from fish, or eggs. uh reindeer, polar bear, walrus? you already did a fox and rabbit so maybe not arctic hare or arctic fox unless you want extras
