Wow, impressive for 13k!
Seems there might be a bug. After I catch a monster, when I go back to the map view, I see extra copies of a lot of buttons.
Also a suggestion: make the movement buttons always in the same place, and organized like a compass rose. It's frustrating when you mouse over the "West" button, and click twice, but suddenly it's an "East" button so you end up going back the way you came accidentally.
An option to speed up the AP would be nice, because it's dreadfully slow. (I get that you might intend it to be a long-form idle game, but in that case it needs to more robustly save your progress. It keeps resetting my progress.)
Anyway, the monster designs are pretty amazing for 13k. It's impressive how varied and different you were able to make them!
