Love the concept. Flying whales is always a win in my book. The building felt very nice and I really liked the Tetris-y aspect of getting new blocks to build with so there's a bit of pre-planning you have to do. It's a shame you didn't get to implement the storm aspect as I'm really curious to see how that would have worked. Great job with what you got done, though!
