Use your mouse to make the boat move in the direction you want. Make sure the boat doesn't hit the brown rocks or the game will stop. White arrows make the boat go faster, green slime makes the boat sink and then come back up again. Remember: put your mouse on the blue sea near to the green area when the boat sinks in the green slime, so you can come back up and move forward!! The shark stop the game if the boa touches it so avoid it! Hit the beach (yellow/sandy colour), to win!
Thanks to Raspberry Pi Foundation for telling me how to make this game. Here's the link: https://projects.raspberrypi.org/en/projects/boat-race :) :P :D
