Very nice game, but I'm only one person... You may want to add an option to choose the number of players. And why do the fish swim only in one direction? Make them swim randomly!

Great game! I like the sand and water changes. For your question, you can check: if(getX()<=0||getX()>=getWorld().getWidth()||getY()>=(water y)) { ... } (water y) is the y of the water. Good luck, Dor.

Awesome game!! I so liked the idea of the game - you need to be against the second player, everyone has advantages : The crab-speed advantage The lobsters-plural advantage. I suggest you to slow down the speed of the crab (or whoever you want to) on the sea - it will be very cool! Addional to it, i saw some fish that were "swimming" on the beach, i suggest to fix this. If you can, try putting some bonuses on the area that will help to the crab and as well to the lobsters. Also, you can do a thing that may kill one of the lobsters or something like that. Very liked that game!
