Release Notes: Fixes for penguin physics and fish collision detection, fixes for many memory leaks, and code optimizations to improve performance.
Release Notes: The install process was fixed by using autoconf and automake. Ice walls and level maps were added. Fish graphics and motion were improved; they now rotate like the penguin. Fish now have really basic AI. The physics were changed to accommodate the new obstacles and prey. The total particles were reduced to ease the processor a bit.
Release Notes: Improved background graphics by adding a mountain, improved penguin physics (especially while jumping out of the water), a new barrier on all sides of the game display, causing the penguin to about-face, new particle splashes and several minor particle improvements, a splash noise and a burping sound at the end of each level, fixing the display text by making text boxes centered and a better shade of blue/green, and a new icon.
