Troubleshooting

If no links to levels appear above, you might have Javascript disabled.

If you get a message "Your browser does not support WebGL" then you will have to upgrade your browser to play.
WebGL is not supported by Internet Explorer, but it should be supported by

Mozilla Firefox since version 4.0
Google Chrome since version 9
Safari since version 5.1 (Only supported on Macs, and you need to turn it on by hand.)

If the game is running too slowly you can increase the framerate by:

pressing Q to switch to simpler graphics
making the window smaller

Raspberry Pi

You can also play this game on a Raspberry Pi running the Raspian "wheezy" operating system.

Installation

Launch a terminal and type

sudo apt-get update
sudo apt-get install penguinspuzzle

This requires the Raspberry Pi to be connected to the internet.
The C source code and game assets are available on the Penguins Puzzle github page.

Play

Launch a terminal and type penguinspuzzle to start the game.

Arrow keys to move.
Spacebar to switch penguins. (Only possible if you have fed the baby penguins with a fish.)

U to undo a move.
R to reset the level.

Z to zoom out for a wider angle view.
N to skip to the next level.
P to change to the previous level.

Escape to quit.

Raspberry Pi Troubleshooting

Make sure that you have a good power supply attached to the Raspberry Pi (and not too much overclocking) or you may find that the Pi crashes as soon as the game starts. For example, when I use a mobile phone charger to power my Pi I find my network and USB devices go down meaning that I am unable to move the penguin even though the 3d graphics are still working.

If you get the error messages:

penguinspuzzle: penguinspuzzle.c:210: init_ogl: Assertion `state->surface != ((EGL_Surface)0)' failed.
penguinspuzzle: audio.c:120: audioplay_create: Assertion `st->audio_render != ((void *)0)' failed.

it probably means you are using the wrong memory split. This game needs at least 64MB of GPU memory so will only work with memory split 128/128 or 192/64. You can change the memory split from a terminal by typing:

cd /boot
sudo cp arm192_start.elf start.elf
sudo reboot

If you get the error message:

error while loading shared libraries: libGLESv2.so: cannot open shared object file

It may mean that your libraries are not up to date. You may be able to fix this from a terminal by typing:

sudo apt-get update
