HI randomphantom, thanks a lot for playing. I agree that the dual purpose theme is a bit weak; part of the idea that didn't end up getting done in time was that there would be multiple whales on screen at once - so you would be trying to catch whales on the mattress at the same time as dodging bricks.
I found that "hug the wall to win" problem too but couldn't think of a solution :< maybe whales should be able to pass the sides of the map, which would count as a miss?
Thanks again!
