One of my graphics for a game called Submarine Chase :
The origanal game is an Atari game called Seaqest.It is cool.You are a submarine,and you pick up scuba divers.Submarine Chase is sort of like that.You pick up fish and crabs for bait for poor fishermen.
Set the difficulty to rookie.Swim through the ocean as you drive around catching sardines.Every now and then,you'll fight a few hammerhead sharks.
Set the difficulty to intermediate.Force your way through the currents as you fight lionfish and cookiecutter sharks.Go around catching decorater
crabs.These are hard to see,so keep a look a look out.
Set the difficulty to master.Speed around in coral reefs catching dolphins and porpoises,fighting Great Whites.Yikes.
Whatever happens,good luck!
