Great stuff! Not sure if it's specific to my game but all the spawned bombs roll off the pier in a fairly consistent way, so I opted to throw clam chowder from the spawn straight at that location until I had enough to buy the next auto fisher or upgrade.
If I was to point at anything, the cool blue colours don't feel particularly summery to me.
Strong sense of progression, fun incrementation of piers and fish. Ended with 1.4 million points in flying sandwiches, and while I wrote this up it's risen to 2.3 million!
Well done!
