Never got attacked for finishing a game xD. 'Congrats you have destroyed the ocean' (Something along those lines)
I absolutely love the art ofcourse but the game mechanics itself is just amazing. Its a simple mechanic but yet so engaging , its really well balanced too. Im currently working on a resource management kinda game and I can see how you could easily over complicate things for yourself and the player!
Congrats on keeping it simple and fun!
