Agartha is an action/adventure fantasy game about a bottlenosed dolphin named Kuros who has to save the world from creatures called the Moirae, whom have invaded Agartha, the last inhabitable place on Earth. For 500 years Agartha was protected by a powerful shield constructed by an ancient civilization called Lemuria. The game involves using your sonar to communicate with dolphins and orcas throughout the game, there will be puzzles to solve and objects to find along the way. The current version has a completable single level and a boss at the end, if you manage to beat the game you'll obtain a bonus item you can use if you wait through the Epilogue and attempt to play the game over. The game was inspired from Sega's Ecco the Dolphin series, however this game is completely unique, because you get to use special items and weapons.
I completed level 3 a while back, problem is when I converted the game to work as a scroller everything got messed up. It'll be a while before this level is operational again.
Nice, although there is way too much contrast and detail in the background sprites, perhaps make your black outlines a dark blue or grey.
