Nice artwork and the UI is self explaining. It was fun to fight the wasp but once they hunted me to the top of the hill this became our final battleground. Above me was a cloud of wasps and I kept on jumping in and hitting A. I thought I could do that forever, because the yellow bar kept on filling. But after 03:25 the game has ended.
May you could add something to prevent the player from fighting always at the same spot. I could imagine that the sting could push the player. But not sure if the play then still would be able to attack.
However: overall a pretty cool and nice looking game :-)
