keep all the same except: wasd for movement. space for bark. smarter fish (less predictable behavior patterns, more random). dog dances in the end of every level.

increase the difficulty and speed of both dog and fishes. fish gets stuck at corners - make it avoid corners with increased speed. add more flow to movement of everything. increase leashes visibility

add arrow/wasd movement. space to bark. fish runs away better. add meta progression with increasing difficulty. decrease the visibility of leashes, and make them connected to random spots outside

Make fish run away. And add more power to bark ability, also make fish move, not teleport instantly. Also give fish other nice animations. Make bark more barky.
