This is a WebGL game.
I am hosting it online here: http://antongerdelan.net/dolphin_rescue/

I have been working with WebGL for about a year and wanted to try making a game. I went Keep-It-Simple-Stupid and did 2d, all on one screen. The game is inspired by the Atari 2600 game SeaQuest, except you are a dolphin!

You rescue sailors from sharks and return them to a boat. When you rescue 5, they can row away, and the next level starts. You run out of air, and have to come up to breathe or you'll die! It gets progressively harder, with more, faster sharks.

To meet the theme I gave the dolphin a special super power - The Sonic Scream - but you can use it only once per game, so you have to be strategic. It knocks out all the sharks, and they go belly-up, but it also refills your air, so you can use it for two types of last-ditch defence.

I added a few interesting bits of scenery for fun, and used a second framebuffer to add in some minimal screen-space special effects.

I hope that you enjoy playing it! I had a great weekend making it.

Please feel free to email me if you want to know more about getting into WebGL programming or OpenGL. I have some OpenGL tutorials on my website. http://antongerdelan.net/
