Yep! The jam's themes are pretty broad! You can basically make the theme mean whatever you want as long as there's some connection to one of the meanings of its words!
I got an dumb idea about a hippo trying to find his friend, with controlls/playability like goat simulator (aka. dumb movement, bugs etc.). Could be fun.
Tho i'll try to make something that's doable and relatively fun (while having atleast basic simulation elements).
