Happy to give hints or solutions if you want. (-: Is it "Out to Pasture" that you're stuck on? (the first level in the farm area)
Thanks for buying the game, and hope you like it!
For Out to Pasture, the rough outline of what you want to do is: (1) Bring the mouse around the edges of the screen to the top area, and have her help the elephant get to the peanut. (2) Send the mouse back around the edges of the screen to the bottom, then enter the fenced-in area from the bottom. (3) Use the mouse to help get the goat to the apple. (4) Finally, have the mouse exit the fenced-in area through the upper mouse hole, which puts her right on the cheese.
(Not sure if that's helpful at all, sorry; let me know if you want a more specific hint.)
If you're interested in modding the game, the code for the level layouts is here and here. There's no level editor, unfortunately; my (somewhat ad-hoc) design process was to brainstorm level ideas in a generic tilemap editor, then just type them by hand into the source code, and tweak them from there as I play-tested.
I can get the goat to the apple and the mouse to the cheese, but I can't get the elephant to the peanut. I almost think its impossible.
If you make a level editor for the game, I can make additional levels. I'm a puzzle designer, but need the level editor to build the levels. Sure I could just change the values in the source code, but that's hard.
From the start of the level, move the mouse east, north, west, then south. Move the elephant east, then north (putting her on the cheese). Move the mouse west. Move the elephant south. Move the mouse east, north, then west. Finally, move the elephant north, then west, putting her on the peanut. You should be able to get the rest from there. (-:
